How to concatenate a string from a list into an instance of a long path in Python

Today the internship company assigned a data Processing task. When I connect a string in a list to a long path, I encounter the following problem:

Import ospath_list = [' first_directory ', ' second_directory ', ' file.txt ']print os.path.join (path_list)

After discovering Os.path.join, it is still a list of strings. That's what I was wondering:

[' First_directory ', ' second_directory ', ' file.txt ']

After thinking about it, Os.path.join's input must be one or more str, not a list. The nature of the list of strings is still lists. instruction to interpret a string list as a str, which is equivalent to os.path.join a single str, and, of course, no change at all.

So I changed the code:

Import ospath_list = [' first_directory ', ' second_directory ', ' file.txt ']# print os.path.join (path_list) head = ' for path ' In path_list:    head = os.path.join (head, path) print head

Finally, the string in the list is concatenated into a full long path:

First_directory/second_directory/file.txt
