我的代码如下:
maybeYes = raw_input("Please enter Yes to continue.")
if maybeYes != "Yes":
print "Try again."
# ask for input again
else:
pass
我想填写哪些内容再次要求输入?

你应该直接在循环中执行raw_input。
while True:
result = raw_input("...")
if result != "Yes":
print "Try again."
continue
else:
break

这将循环打印wrong
,直到用户输入yes
,Yes
,YEs
,YES
,yEs
或{{1}在检查yeS
之前输入被转换为全部大写,那么你的代码可以继续......
YES
输出:
while raw_input("Please enter Yes to start: ").upper() != 'YES':
print 'Wrong'
print 'Correct'
#Carry on here

在我看来,你想要一个无限循环。
maybeYes = raw_input("Please enter Yes to continue.")
while maybeYes != "Yes":
maybeYes = raw_input("Please try again.")
但是,您始终可以添加计数器/转义符。
maybeYes = raw_input("Please enter Yes to continue.")
attempts = 0
while maybeYes != "Yes" and attempts < 10:
maybeYes = raw_input("Please try again.")
attempts += 1
