replace python's depricated dict.has_key(k) with "k in dict" with a regex

has_key

Vim regex
:%s/\([^ ]\+\)\.has_key(\(.\{-}\))/\2 in \1/g

sed regex
s/\([^ ]\+\)\.has_key(\([^)]*\))/\2 in \1/g

And here is the string.method(object, ...) -> object.method(...)
Specificlaly for string.replace():
Vim regex:
%s/string\.replace(\(.\{-}\), /\1.replace(/
sed regex:
s/string\.replace(\([^,]*\), /\1.replace(/

string.method(object) -> object.method()
Specifically for string.lower():
sed regex:
s/string\.lower(\(.*\))/\1.lower()/
