Python 条件判断 和循环

# 条件派单 if else
print(‘条件派单 if else‘)
# s = input(‘请输入生日年号：‘)
# birth = int(s)
birth = 1991
if birth > 2000:
    print(‘00后‘)
else:
    print(‘00前‘)

# for 循环
print(‘for 循环‘)
sum = 0
for i in range(101):
    sum = sum + i
print("0到100的整数相加之和：", sum)

# while 循环
print(‘while 循环‘)
n = 100
while n > 0:
    n = n - 1
    if (n < 10):
        break
    # continue
print(n)
