Python endswith()
方法用于判断字符串是否以指定后缀结尾，如果以指定后缀结尾返回True，否则返回False。可选参数"start"与"end"为检索字符串的开始与结束位置。如果字符串含有指定的后缀返回True，否则返回False。
语法：str.endswith(suffix[, start[, end]])

题目：游戏规则是每个员工从1开始依次数数，当数到尾数是7的数或7的倍数时，则该员工不报出该数，而是拍一下腿。凡是出错的员工将会受到小惩罚——做10个俯卧撑。
# 方法一 count = 99 for n in range(1, 100): if n % 7 == 0 or str(n).endswith('7'):
# 描述：判断字符串是否以指定字符或子字符串结尾。 continue count = count - 1 print(
'本次游戏中所有参与员工从1数到99共拍了{}次'.format(count)) # 方法二 count = 0 for n in range(1, 100):
if n % 7 == 0 or str(n).endswith('7'): count = count + 1 print(
'本次游戏中所有参与员工从1数到99共拍了{}次'.format(count))
结果：
