This function has a while loop that should be broken after the user inputs "0", but the loop isn't broken until the second time the user inputs "0". I'm not sure why, and don't know how to resolve this.

To check whether the numbers are coprime or not.
I've actually used an easier logic here which makes complete sense, but for some reason, I'm not able to get the correct answer using this code. Please do check the code out and let me know what you think about it :)
m = int(input())
n = int(input())
setm = set()
setn = set()
for i in range(1,m+1):
if (m%i==0):
setm.add(i)
for j in range(1,n+1):
if (n%j==0):
setn.add(j)
if setm.intersection(setn) == '1':
print('Coprime')
else:
print('Not coprime')
This line
if setm.intersection(setn) == '1':
does not do the comparison correctly. There are many ways to fix it - for example, you could check the length of the intersection:
if len(setm.intersection(setn)) == 1:
The idea behind this comparison is that 1 will always be in both set of divisors for mathematical reasons, so if the sets intersect on a single item, it must be 1.
P.S. Note that your algorithm would incorrectly identify two 1s as coprime; this should be fixed with a few additional checks.
m = int(input())
n = int(input())
setm = set()
setn = set()
for i in range(1,m+1):
if (m%i==0):
setm.add(i)
for j in range(1,n+1):
if (n%j==0):
setn.add(j)
if setm.intersection(setn) == {1}:
print('Coprime')
else:
print('Not coprime')
Intersection returns a set.
I have a set of points and I want to create line / road network from those points. Firstly, I need to determine the closest point from each of the points. For that, I used the KD Tree and developed a code like this:
def closestPoint(source, X = None, Y = None):
df = pd.DataFrame(source).copy(deep = True) #Ensure source is a dataframe, working on a copy to keep the datasource
if(X is None and Y is None):
raise ValueError ("Please specify coordinate")
elif(not X in df.keys() and not Y in df.keys()):
raise ValueError ("X and/or Y is/are not in column names")
else:
df["coord"] = tuple(zip(df[X],df[Y])) #create a coordinate
if (df["coord"].duplicated):
uniq = df.drop_duplicates("coord")["coord"]
uniqval = list(uniq.get_values())
dupl = df[df["coord"].duplicated()]["coord"]
duplval = list(dupl.get_values())
for kq,vq in uniq.items():
clstu = spatial.KDTree(uniqval).query(vq, k = 3)[1]
df.at[kq,"coord"] = [vq,uniqval[clstu[1]]]
if([uniqval[clstu[1]],vq] in list(df["coord"]) ):
df.at[kq,"coord"] = [vq,uniqval[clstu[2]]]
for kd,vd in dupl.items():
clstd = spatial.KDTree(duplval).query(vd,k = 1)[1]
df.at[kd,"coord"] = [vd,duplval[clstd]]
else:
val = df["coord"].get_values()
for k,v in df["coord"].items():
clst = spatial.KDTree(val).query(vd, k = 3)[1]
df.at[k,"coord"] = [v,val[clst[1]]]
if([val[clst[1]],v] in list (df["coord"])):
df.at[k,"coord"] = [v,val[clst[2]]]
return df["coord"]
The code can return the the closest points around. However, I need to ensure that no double lines are created (e.g (x,y) to (x1,y1) and (x1,y1) to (x,y)) and also I need to ensure that each point can only be used as a starting point of a line and an end point of a line despite the point being the closest one to the other points.
Below is the visualization of the result:

What I want
I've also tried to separate the origin and target coordinate and do it like this:
df["coord"] = tuple(zip(df[X],df[Y])) #create a coordinate
df["target"] = "" #create a column for target points
count = 2 # create a count iteration
if (df["coord"].duplicated):
uniq = df.drop_duplicates("coord")["coord"]
uniqval = list(uniq.get_values())
for kq,vq in uniq.items():
clstu = spatial.KDTree(uniqval).query(vq, k = count)[1]
while not vq in (list(df["target"]) and list(df["coord"])):
clstu = spatial.KDTree(uniqval).query(vq, k = count)[1]
df.set_value(kq, "target", uniqval[clstu[count-1]])
else:
count += 1
clstu = spatial.KDTree(uniqval).query(vq, k = count)[1]
df.set_value(kq, "target", uniqval[clstu[count-1]])
but this return an error
IndexError: list index out of range
Can anyone help me with this? Many thanks!
Answering now about the global strategy, here is what I would do (rough pseudo-algorithm):
current_point = one starting point in uniqval
while (uniqval not empty)
construct KDTree from uniqval and use it for next line
next_point = point in uniqval closest to current_point
record next_point as target for current_point
remove current_point from uniqval
current_point = next_point
What you will obtain is a linear graph joining all your points, using closest neighbors "in some way". I don't know if it will fit your needs. You would also obtain a linear graph by taking next_point at random...
It is hard to comment on your global strategy without further detail about the kind of road network your want to obtain. So let me just comment your specific code and explain why the "out of range" error happens. I hope this can help.
First, are you aware that (list_a and list_b) will return list_a if it is empty, else list_b? Second, isn't the condition (vq in list(df["coord"]) always True? If yes, then your while loop is just always executing the else statement, and at the last iteration of the for loop, (count-1) will be greater than the total number of (unique) points. Hence your KDTree query does not return enough points and clstu[count-1] is out of range.
I am creating some code for a school project, and for a module I use later on, I need to know what the intensity to end on(end_intensity) is. When the code is run, the end_intensity still comes out as unassigned, this means that the
if client_intensity == "High":
line is never being run.Can someone please explain why it won't assign .
correct = False
end_intensity = "Unassigned"
while correct != True:
id_search = input("please enter the Client ID of the client you wish to record results for:")
# open file, with will automatically close it for you
with open("text_documents/clientIntensity.txt") as f:
user_found = False
# loop over every line
for line in f:
client,intensity = line.split(",")
if id_search == client:
correct = True
user_found = True
intensity = str (intensity)
client_intensity = intensity
#assigns which one is the end intensity
if intensity == 'High':
end_intensity = 'Moderate'
elif intensity == 'Moderate':
end_intensity = 'High'
if user_found == False:
print("I'm sorry no results we're found for that ID, please try again\n")
print(end_intensity)
The text document is in this format:
NeQua,High
ImKol,Moderate
YoTri,Moderate
(I apologize for the numbers for the text document formatting,stack overflow would only let me show it like that)
Any help would be appreciated,Thanks

the error is on line 10. no clue why it crashes. the equals sign is highlighted red once it is run.
code as follows:
import random
question = 1
correct = 0
while question < 10:
a = random.randint(1, 12)
b = random.randint(1, 12)
answer = input(a, 'x', b, '=')
if 'answer' = 'a*b':
print ('correct!')
correct = correct+1
else:
print ('Incorrect\nthe correct answer was', a*b)
print ('You got', correct, 'out of 10 correct')
Change your if statement to this:
if answer == a*b:
Using = assigns the value where == tests equality.
The other issue is that you have too many arguments for the input function. Input takes one argument, that is a string to output to the command line to show the user. Then the input comes in as a string and you cannot directly compare string's to integers so you need to convert the string to an integer.
answer = input("Enter in the answer for {} * {}".format(a,b))
answer = int(answer)
I was trying to solve Challenge 2 at the end of the classes chapter (Chapter 8) in "Python Programming for the Absolute Beginner" which is stated as:
Write a program that simulates a television by creating it as an object. The user should be able to enter a channel number and raise or lower the volume. Make sure that the channel number and the volume level stay within valid ranges.
I keep getting: TypeError: 'int' object is not callable, which at this stage just isn't very helpful.
I'm a beginner but I've seen something really similar working (see at the bottom right below my code) and nearly went as far as nearly copying that code. Could somebody maybe explain what's wrong with this and how I can get it to work?
Here's the complete error:
Traceback (most recent call last):

My code is below,
Thanks
class Television(object):

self.channel = channel

Why does the following work instead? To me, it looks pretty similar to what I've done.
class Critter(object):
"""A virtual pet"""
def __init__(self, hunger = 0, boredom = 0):
self.hunger = hunger
self.boredom = boredom
def eat(self, food = 4):
print("Brruppp. Thank you.")
self.hunger += food
if self.hunger < 0:
self.hunger = 0
crit = Critter()
print(crit.hunger)
crit.eat(food = int(input("how much do you want to feed him?")))
print(crit.hunger)
The problem is you are defining a method with the same name as a property. That is, you're saying Television.channel is an int, but later you are binding a method to that name.
