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."

CodePudding user response：

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.

CodePudding user response：

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.

CodePudding user response：

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)
