Can I safely remove all u-strings from a project that will only use python 3?
Question:
I work on a project that includes many u"string" in its codebase,
I want to know if I can safely remove the u in front of all those strings knowing that the project will only use Python 3 from now on (it used to use both python 2 and 3)
I have only one source that says :
"The string prefix u is used exclusively for compatibility with Python
2."
Answers:
Yes, you can. The sentence you quoted means that u"string" is in python3 only for compatibility.
In python 3 all strings are unicode so the u is redundant.
Yes. I think you can. Unicode strings are not necessary in Python 3, because all strings are stored as Unicode by default, as stated here.
I did run test using 2to3 tool and it did change u-string to normal string, ustring.py file before
x = u"string"
print(x)
after 2to3 -w ustring.py
x = "string"
print(x)
