Subject: A question about string and float number
Hi all,
I am new of python. Could anyone help me a question as below?
Is there any function that can judge a string s is a float number or not? FOr
example, if s = '1.232' or s='1e+10', then it returns true, otherwise, it will
return false.
isdigit() in string doesn't work. float() will throw an exception and I just
need true or false as result.
Thanks a lot in advance,
Wei
