I get a series, s3, of type
timedelta64[ns]
0 385 days, 04:10:36
1 57 days, 22:54:00
2 642 days, 21:15:23

I misspelled the name of the virtualenv while initializing it using:
$ virtualenv vnev
I actually intended to create the environment with the name venv.

$ mv vnev venv
$ . venv/bin/activate

I am trying to set the format to two decimal numbers in a matplotlib subplot environment. Unfortunately, I do not have any idea how to solve this task.
To prevent using scientific notation on the y-axis I used ScalarFormatter(useOffset=False) as you can see in my snippet below. I think my task should be solved by passing further options/arguments ….

I currently have a dataframe consisting of columns with 1’s and 0’s as values, I would like to iterate through the columns and delete the ones that are made up of only 0’s. Here’s what I have tried so far:
ones = []
zeros = []
for year in years:
for i in range(0,599):
if year[str(i)].values.any() == 1:

What is best pure Python implementation to check if a string contains ANY letters from the alphabet?
string_1 = “(555).555-5555”
string_2 = “(555) 555 – 5555 ext. 5555
Where string_1 would return False for having no letters of the alphabet in it and string_2 would return True for having letter.
