I have been trying to make something like an encoder:
here is my idea
dict = {
1: "!",
2: "#"
}
in = 21 # Input number in
out = ?
print(out) # Returns "#!"
Is there any way I could perform this?
What you want is exactly the translate function of str:
x="12"
y="!#"
in=12
txt=str(in)
mapping = txt.maketrans(x, y)
out=txt.translate(mapping)

I am trying to assert a list using match contains any, match each but it is not working.
def actualList = ["CABLE_MODEM","SET_TOP_BOX","SET_TOP_BOX","CABLE_MODEM","CBE"]
def expectedList = ["CABLE_CARD","SET_TOP_BOX","CABLE_MODEM","MTA","OTHER","IP_SET_TOP_BOX"]
match each actualList contains any expectedList
Basically, every value of the actualList should be any one of the expectedList value. But it is directly comparing the first value of the 2 lists. Kindly help me
I'm not sure I understand the question. But sometimes these crazy assertions are best done in JS:
* def actualList = ["CABLE_MODEM","SET_TOP_BOX","SET_TOP_BOX","CABLE_MODEM","CBE"]
* def expectedList = ["CABLE_CARD","SET_TOP_BOX","CABLE_MODEM","MTA","OTHER","IP_SET_TOP_BOX"]
* def unexpected = actualList.filter(x => !expectedList.includes(x))
* match unexpected == []
Please take the help of a friend who knows JS if the above is not clear.
EDIT: for completeness, here's the "karate style" way to solve this. For more complex custom checks, karate.match() can be used.
* def valid = function(x){ return expectedList.includes(x) }
* match each actualList == '#? valid(_)'
I rather have this ugly way of building a string from a list as:
val input = listOf("[A,B]", "[C,D]")
val builder = StringBuilder()
builder.append("Serialized('IDs((")
for (pt in input) {
builder.append(pt[0] + " " + pt[1])
builder.append(", ")
}
builder.append("))')")
The problem is that it adds a comma after the last element and if I want to avoid that I need to add another if check in the loop for the last element.
I wonder if there is a more concise way of doing this in kotlin?
EDIT
End result should be something like:
Serialized('IDs((A B,C D))')
In Kotlin you can use joinToString for this kind of use case (it deals with inserting the separator only between elements).
It is very versatile because it allows to specify a transform function for each element (in addition to the more classic separator, prefix, postfix). This makes it equivalent to mapping all elements to strings and then joining them together, but in one single call.
If input really is a List<List<String>> like you mention in the title and you assume in your loop, you can use:
input.joinToString(
prefix = "Serialized('IDs((",
postfix = "))')",
separator = ", ",
) { (x, y) -> "$x $y" }
Note that the syntax with (x, y) is a destructuring syntax that automatically gets the first and second element of the lists inside your list (parentheses are important).
If your input is in fact a List<String> as in listOf("[A,B]", "[C,D]") that you wrote at the top of your code, you can instead use:
input.joinToString(
prefix = "Serialized('IDs((",
postfix = "))')",
separator = ", ",
) { it.removeSurrounding("[", "]").replace(",", " ") }
val input = listOf("[A,B]", "[C,D]")
val result =
"Serialized('IDs((" +
input.joinToString(",") { it.removeSurrounding("[", "]").replace(",", " ") } +
"))')"
println(result) // Output: Serialized('IDs((A B,C D))')
Kotlin provides an extension function [joinToString][1] (in Iterable) for this type of purpose.
input.joinToString(",", "Serialized('IDs((", "))')")
This will correctly add the separator.
This question already has an answer here:
Change type from string to float/double for a key value of any json object in an array
(1 answer)
Closed 1 year ago.
I'm trying to convert an Array to string using a simple js function placed in the reusable feature file. I don't see any reason why the array is not getting converted to a string when I try to run the same function on the console it works without any issue.
Can anyone suggest a way to get this issue sorted?
"""
* def formatter = function(str){
var formatstring = str.toString();
return formatstring
}
"""
feature file
* def format = call read('../common/resuable.feature)
* def result = format.formatter(value)
* print result
Input = ["ID3:Jigglypuff(NORMAL)"]
Actual result = ["ID3:Jigglypuff(NORMAL)"]
Expected result = ID3:Jigglypuff(NORMAL)

Sorry, if you print an array, it will have square-brackets and all, that's just how it is.
Please unpack arrays if you want the plain string / content:
* def input = ["ID3:Jigglypuff(NORMAL)"]
* def expected = input[0]
I have been looking for a solution everywhere on the internet but nowhere I can see a single script which lets me read the name of a variable as a string in Godot 3.1
What I want to do:
Save path names as variables.
Compare the name of the path variable as a string to the value of another string and print the path value.
Eg -
var Apple = "mypath/folder/apple.png"
var myArray = ["Apple", "Pear"]
Function that compares the Variable name as String to the String -
if (myArray[myposition] == **the required function that outputs variable name as String**(Apple) :
print (Apple) #this prints out the path.
Thanks in advance!
I think your approach here might be a little oversimplified for what you're trying to accomplish. It basically seems to work out to if (array[apple]) == apple then apple, which doesn't really solve a programmatic problem. More complexity seems required.
First, you might have a function to return all of your icon names, something like this.
func get_avatar_names():
var avatar_names = []
var folder_path = "res://my/path"
var avatar_dir = Directory.new()
avatar_dir.open(folder_path)
avatar_dir.list_dir_begin(true, true)
while true:
var avatar_file = avatar_dir.get_next()
if avatar_file == "":
break
else:
var avatar_name = avatar_file.trim_suffix(".png")
avatar_names.append(avatar_name)
return avatar_names
Then something like this back in the main function, where you have your list of names you care about at the moment, and for each name, check the list of avatar names, and if you have a match, reconstruct the path and do other work:
var some_names = ["Jim","Apple","Sally"]
var avatar_names = get_avatar_names()
for name in some_names:
if avatar_names.has(name):
var img_path = "res://my/path/" + name + ".png"
# load images, additional work, etc...
That's the approach I would take here, hope this makes sense and helps.
I think the current answer is best for the approach you desire, but the performance is pretty bad with string comparisons.
I would suggest adding an enumeration for efficient comparisons. unfortunately Godot does enums differently then this, it seems like your position is an int so we can define a dictionary like this to search for the index and print it out with the int value.
var fruits = {0:"Apple",1:"Pear"}
func myfunc():
var myposition = 0
if fruits.has(myposition):
print(fruits[myposition])
output: Apple
If your position was string based then an enum could be used with slightly less typing and different considerations.

Can't you just use the str() function to convert any data type to stirng?
var = str(var)
how dows this work in R...
I am using a package (zoo 1.6-4) that defines a S3 class for time series sets.
I am writing a derived class where I want to override a few methods and can't get past this one:[.zoo!
in my derived class rows are indexed by timestamp, like in zoo, but differently from zoo, I allow only POSIXct values in the index. my users will be selecting columns all of the time, while slicing series only occasionally so I want to offer obj[name] instead of obj[, name].
my objects have class c("delftfews", "zoo").
but...
how do I override a method?
I tried this:
"[.delftfews" <- function(x, i, j, drop=TRUE, ...) {
if (missing(i)) return(NextMethod())
if (all(class(i) == "character") && missing(j)) {
return(NextMethod('[', x=x, i=1:NROW(x), j=i, drop=drop, ...))
}
NextMethod()
}
but I get this error: Error in rval[i, j, drop = drop., ...] : incorrect number of dimensions.
I have solved by editing the source from zoo: I removed those ..., but I don't get why that works. anybody can explain what is going on here?
The problem is that with the above definition of [.delftfews this code:
library(zoo)
z <- structure(zoo(cbind(a = 1:3, b = 4:6)), class = c("delftfews", "zoo"))
z["a"]
# generates this call: `[.zoo`(x = 1:6, i = 1:3, j = "a", drop = TRUE, z, "a")
Your code does work as is if you write the call like this:
z[j = "a"]
# generates this call: `[.zoo`(x = z, j = "a")
I think what you want is to change the relevant line in [.delftfews to this:
return(NextMethod(.Generic, object = x, i = 1:NROW(x), drop = drop))
# z["a"] now generates this call: `[.zoo`(x = z, i = 1:3, j = "a", drop = TRUE)
A point of clarification: allowing only POSIXct index values does not allow indexing columns by name only. I'm not sure how you arrived at that conclusion.
You're overriding zoo correctly, but I think you misunderstand NextMethod. The error is caused by if (missing(i)) return(NextMethod()), which calls [.zoo if i is missing, but [.zoo requires i because zoo's internal data structure is a matrix. Something like this should work:
if (missing(i)) i <- 1:NROW(x)
though I'm not sure if you have to explicitly pass this new i to NextMethod...
You may be interested in the xts package, if you haven't already taken a look at it.
