Python 确定第一个数字

我试图确定字符串中的第一个字符是否以特定字符开头。 比如：

在本例中，我想知道数字的字符串是否以0开头。python中是否有内置函数可以确定字符串是否以特定字符开头？我必须使用split来解决这个问题吗？

返回一个字符串

字符串永远不等于数字

>>> '0' == 0
False

将字符串与字符串进行比较。例如，要检查字符串是否以特定的子字符串开头，请使用：

当您输入字符串时，您正在输入字符串

number = raw_input('What is your answer?')

所以您可以检查第一个元素，如

number = raw_input('What is your answer?')
try:
    if number[0]=='0':
        print "First element is 0"
        #Put your code
    else:
        print "First element is not 0"
        #Do something else
except IndexError:
    print "Input was null"

number = raw_input('What is your answer?')

number = raw_input('What is your answer?')
try:
    if number[0]=='0':
        print "First element is 0"
        #Put your code
    else:
        print "First element is not 0"
        #Do something else
except IndexError:
    print "Input was null"
