python条件判断

1 条件判断

ex:

age = 20
if age>=18:
print('your age is ',age)
print('adult')

else:
print('your age is ',age)
print('teenager')

2 input,读取用户的输入

ex:

bitrh = input('birth:')

3 for...in循环

ex: names = ['Mical','Bob','Tracy']

for name in names:

printf(name)

4 range()函数，可以生成一个整数序列

ex：range(5) ->0,1,2,3,4

5 while循环
