I am working on migrating an old Python code base to Python3.
There are many strings which have the "u" prefix. Example u'Umlaut üöö'
Is there an automated way to remove the leading "u"?
A simple regex is does not work:
u'schibu'
: u'
at the end must not get removed.
Example2:
Multiline: '''foo
schibu'''
Is there maybe a way which works without a regex, but via parsing the python syntax?
Using 2to3 tool unicode
fixer should do that.
unicode
Renames unicode to str.
Dry run with sample spam.py
file
eggs = u'foo'
in shell:
$ 2to3 --fix unicode spam.py
output
root: Generating grammar tables from /usr/lib/python2.7/lib2to3/PatternGrammar.txt
