遍历列表:
list= ['a', 'b', 'c', 'd', 'e’]
list1 = []
for i in range(0, len(list)):
list1=list[i]
print(list1)
list= ['a', 'b', 'c', 'd', 'e']
for i in range(0, len(list)):
print(list[I])
Break 和continue
list= ['a', 'b', 'c', 'd', 'e','f','g']
for i in range(0, len(list)):
if list[i]=='d':
continue
print(list[I])
list= ['a', 'b', 'c', 'd', 'e','f','g']
for i in range(0, len(list)):
if list[i]=='d':
break
print(list[I])
for i in 后面可以对列表、字符串、元组、字典、文件进行遍历
for i in range(0,1) or(5) or(0,len(list))etc 后面只能接数字或者数字区间
元组的值是不能进行修改的
字典可以通过key值来取的value值
