check if a string is float python

by 
def is_number(x):
    '''
        Takes a word and checks if Number (Integer or Float).
    '''
    try:
        # only integers and float converts safely
        num = float(x)
        return True
    except ValueError as e: # not convertable to float
        return False

Here is what the above code is Doing:
1. We define a function called is_number.
2. We try to convert the word to a float.
3. If the word can be converted to a float, we return True.
4. If the word cannot be converted to a float, we return False.
