I found an interesting problem on https://leetcode.com/problems/valid-number/:
Validate if a given string is numeric.

Some examples:
"0" => true
" 0.1 " => true
"abc" => false
"1 a" => false
"2e10" => true

Note: It is intended for the problem statement to be ambiguous. You should gather all requirements up front before implementing one.

Update (2015-02-10):
The signature of the C++ function had been updated. If you still see your function signature accepts a const char * argument, please click the reload button to reset your code definition.

I tried it in Python, but could not do it. Can you solve it?

 ... Can you provide a the Python program you requested?

             return True
         except:
             return False
