Find the leftmost digit that occurs in a given string.

Example

For inputString = "var_1__Int", the output should be
firstDigit(inputString) = ‘1‘;
For inputString = "q2q-q", the output should be
firstDigit(inputString) = ‘2‘;
For inputString = "0ss", the output should be
firstDigit(inputString) = ‘0‘.

我的解答：

def firstDigit(inputString):
    return [i for i in inputString if i.isdigit()][0]

def firstDigit(inputString):
    for i in inputString:
        if i.isdigit():
            return i
