I've got trouble to verify a path who contains variables using "os.path.exists(path)". Which character should be used to put the content of vars in path and then verify the path?

nb : EOF Error...

Thanks you. 

path = (C:\programm\.....\+var1+\+var2+\)
isExist = os.path.exists(path)
if (isExist == false):
    os.mkdirs(path)
else:
    print (" ")

import os
# change \ to \\
path = ("C:\\programm\\.....\\+var1+\\+var2+\\")
isExist = os.path.exists(path)
# change false to False
if (isExist == False):
    # change os.mkdir to os.makedirs
    os.makedirs(path)
else:
    print (" ")

  • Using `exists` like that is subject to a race condition, because another process could create the directory in between the two operations. It's more robust to eliminate the `exists` check by putting `mkdir/makedirs` in a `try/except` and catching `FileExistsError`. – ekhumoro Mar 11 '20 at 11:29

    Please add some explanation with your code. – Itamar Mushkin Mar 11 '20 at 11:33
  • thought that was not so hard to understand... well thanks – S. Me Mar 11 '20 at 12:19

modify value of path variable as,

path = (C:\programm\.....\+var1+\+var2+\)

backslash is a escape character in programming languages, so to print backslash, we need to put double backslash(\) in variable value or print statement.

  • Just see that we can use a simple slash instead of double backslash and escape var in path with this : " . Example : path = (C:/.../.../"+var1+"/..../"+var2"/) – S. Me Mar 11 '20 at 12:43
