I am variable which is a file path ie C:\temp
Inside temp i have csv files all with the format number01.csv number02.csv and so on x amount of times

what my script does is read the original csv file from temp do some modifications and then creates an updated csv file.

right now each time i have to change the file path indivdually but i am looking for a way to automate it

this is what I am trying to do

numbers= [5,6,7,8]
for x in number:
    file_name =  'C:\\temp\number{x}.csv'
    output_file = 'C:\\temp\number{x}_rev.csv'

how can i add an integer value in the middle of a string in python3?

You need to use an f-string `f'...'`. Try `f'C:\\temp\number{x}.csv'` – flakes Nov 25 '20 at 00:06

You need to double up the backslashes everywhere, not just the first time. – Mark Ransom Nov 25 '20 at 00:07
@DYZ that link does not answer the question. They want string interpolation https://www.python.org/dev/peps/pep-0498/ – flakes Nov 25 '20 at 00:09
@flakes Which is one of the answers. – DYZ Nov 25 '20 at 00:09
