I am having trouble creating a data frame with the following data:
Force (N) microstrain1 microstrain2 microstrain3 microstrain4 microstrain5
24.838 9.689 -20.299 19.785 15.601 -7.681
49.691 22.610 -40.797 41.304 32.200 -15.332
75.309 33.357 -61.678 62.512 48.726 -22.422
97.227 41.944 -80.524 81.011 62.266 -30.228
121.641 52.692 -100.775 100.703 77.248 -36.884
Every time I try to use a delimiter I get the following message:
/Users/macbookpro/PycharmProjects/Projects/Lab_3/Bending.py:5: ParserWarning: Falling back to the 'python' engine because the 'c' engine does not support regex separators (separators > 1 char and different from '\s+' are interpreted as regex); you can avoid this warning by specifying engine='python'.
df1 = pd.read_csv('MEE322-thurs_1040_group1_9.5cm.txt',delimiter=' ')
Did you try the python engine instead of the c engine?:
df1 = pd.read_csv('MEE322-thurs_1040_group1_9.5cm.txt', delimiter=' ', engine='python')

I have a variable with a list on it and I need to use its value for my find option. I get an error when I set my id_user to id_u.
Here is the list
id_u = user_key[0]
This is my SELECT and WHERE
find = ("SELECT * FROM hashtags WHERE id_user=id_u")
You have to concatenate SELECT string with variable value.
Try like this:
id_u = user_key[0]
find = ("SELECT * FROM hashtags WHERE id_user=" + id_u)

I'm trying to understand a code from my teacher and he uses MonthBegin(1) from Pandas to calculate the distance from months on a data frame.
I already tried to read the documentation but its description is too simple and there are no examples :(
The code that I'm trying to understand is:
month_distance = int(((df['ResearchDate'][index + 1] + MonthBegin(1)) - (df['ResearchDate'][index] + MonthBegin(1))).days / 31)
Consider the following code:
import pandas as pd
from pandas.tseries.offsets import MonthBegin
data = pd.date_range(start='1/1/2021', periods=10, freq="8d")
df = pd.DataFrame(data)
df["mb1"] = df[0] + MonthBegin(1)
print(df)
Basically it is being used so your teacher can get the difference in number of months by rounding dates to the next month's beginning.

I have a bunch of SQL scripts that do this:
COALESCE([18], 0),COALESCE([19], 0),COALESCE([20], 0),COALESCE([21], 0) ect
Is there a way to use regex to update them to do this:
COALESCE([18], 0) as [18], COALESCE([19], 0) as [19], COALESCE([20], 0) as [20], COALESCE([21], 0) as [21]
Find:
[^()]+\(\[(\d+)\][^)]+\)
Replace:
$0 AS [$1]
Demo:
Debuggex Demo
(.*?(\[\d+\]).*?\))
This will work as well.
See demo.

I'm looking for a Julia function which, when applied to a module name, lists the functions available through the module.
Basically, I don't want to scour through source code and I've noticed that the documentation for many modules usually doesn't have everything.
names works, mostly:
module MyMod
test() = 3
foo() = 4
end
names(MyMod, true)
gives me
4-element Array{Symbol,1}:
:eval
:test
:foo
:MyMod
Just need to strip out the module name and eval
Expanding on the previous answer slightly, the following seems to work:
function module_functions(modname)
list = Symbol[]
for nm in names(modname)
typeof(eval(nm)) == Function && push!(list,nm)
end
return list
end
Example:
using PyPlot
module_functions(PyPlot)
produces the following output in the REPL:
165-element Array{Symbol,1}:
:contourf
:over
:xticks
:ion
:flag
:summer
:stackplot
:tricontourf
:minorticks_on
:gray
:savefig
:errorbar
:box
:figure
:vlines
:subplot_tool
:jet
⋮
:locator_params
:imshow
:pie
:sci
:axhline
:streamplot
:hist2d
:copper
:text3D
:Axes3D
:loglog
:zticks
:hexbin
:pcolor
:semilogy

Here is my code:
- (CGFloat)layoutManager:(NSLayoutManager *)layoutManager lineSpacingAfterGlyphAtIndex: (NSUInteger)glyphIndex withProposedLineFragmentRect:(CGRect)rect
{
return 20;
}
def layoutManager(layoutManager, lineSpacingAfterGlyphAtIndex:glyphIndex withProposedLineFragmentRect:rect)
20
end
Start here: http://www.rubymotion.com/developer-center/guides/getting-started/
Should be something like this:
def layoutManager(layoutManager, lineSpacingAfterGlyphAtIndex: nil, withProposedLineFragmentRect: nil)
return 20.0
end
Check the repo for examples.
Also, that method should return a float, not an int.
