我的朋友让我用Python为她的班级做一个简单的数学测试。当用户出错时,问题将无限重复。
test1 = raw_input ("How much is 3+23?")
if (test1 == '26'):
print "Well done!"
else:
print "Try again. I'm sure your brain will function correctly this time."
test1 = raw_input ("How much is 3+23?")
我试过这样做,但这个问题只重复了两次。有没有办法进行无限重试而不必输入“game1 = raw_input(”多少是3 + 23?“)”一遍又一遍?
此外,一些问题可能只有有限的重试次数。我可以告诉Python我希望这部分代码循环多少次?
提前致谢!

对于无限循环,请使用while-loop:
# This will run until input = '26'
while True:
test = raw_input("How much is 3+23?")
if test == '26':
# If we got here, input was good; break the loop
break
print "Try again. I'm sure your brain will function correctly this time."
print "Well done!"
# This runs for 10 times max
for _ in xrange(10):
test = raw_input("How much is 3+23?")
if test == '26':
print "Well done!"
break
print "Try again. I'm sure your brain will function correctly this time."
