How to insert the value of a string variable within a string which is part of an list in Python?

Question

How do I insert the value of a string variable within a string which is not going into Python's print method but going into a list of strings?

#!/usr/bin/env python3

some_var="/some/path/to/somewhere"
my_list_of_paths = ['A=/a/b/c', 'B=/b/c/d', 'C=some_var']

print(my_list_of_paths)

print(my_list_of_paths) should print ['A=/a/b/c', 'B=/b/c/d', 'C=/some/path/to/somewhere'] but it prints ['A=/a/b/c', 'B=/b/c/d', 'C=some_var'] which is not the intention here.

Ah I need to prepend that with `f`. I was trying 'C={some_var}'. Thanks. It works — TheWaterProgrammer, May 27 '21 at 07:50
BTW, you have a [list](https://docs.python.org/3/library/stdtypes.html#typesseq-list) here. An [`array`](https://docs.python.org/3/library/array.html) is something different. — Matthias, May 27 '21 at 07:51
Woops! Yes. I modified the question to call it a list. Thanks — TheWaterProgrammer, May 27 '21 at 07:53
For the sake of understanding SO rules, why shouldn't there be an answer to this question and only a comment? Is it because the answer is too simple? — TheWaterProgrammer, May 27 '21 at 07:55
@TheWaterProgrammer, it's okay to write an answer to this question. But I'm 99% sure that it's duplicate, so it will be closed soon. — Olvin Roght, May 27 '21 at 07:55

This should work:

#!/usr/bin/env python3

some_var="/some/path/to/somewhere"
my_list_of_paths = ['A=/a/b/c', 'B=/b/c/d', 'C=' + some_var]

print(my_list_of_paths)

The following way of insert the string value with f notation also works:

#!/usr/bin/env python3

some_var="/some/path/to/somewhere"
my_list_of_paths = ['A=/a/b/c', 'B=/b/c/d', f'C={some_var}']

print(my_list_of_paths)
