Code：
print('------------------------------------------------------')
# for...in.循环:依次把list或tuple中的每个元素迭代出来
names = ['Michael', 'Bob', 'Tracy']
for name in names:
print(name)
print('------------------------------------------------------')
num = 0
for x in [1,2,3,4,5,6,7,8,9,10]:
num = num + x
print('1 + 2 + 3 + 4 .. + 10 =',num)
print('------------------------------------------------------')
print('list(range(5)) :',list(range(5)))
#Python提供一个range()函数，可以生成一个整数序列，再通过list()函数可以转换为list
print('------------------------------------------------------')
num = 0
for x in range(101):
num = num + x
print(num)
print('------------------------------------------------------')
#while循环，只要条件满足，就不断循环，条件不满足时退出循环
#计算100以内所有奇数之和
num = 0
n = 99
while n > 0:
num = num + n
n = n - 2
print(num)
print('------------------------------------------------------')
#break:break语句可以提前退出循环
n = 1
while n <= 100:
if n > 10: # 当n = 11时，条件满足，执行break语句
print('break!')
break # break语句会结束当前循环
print(n)
n = n + 1
print('END')
print('------------------------------------------------------')
#continue:在循环过程中，也可以通过continue语句，跳过当前的这次循环，直接开始下一次循环
n = 0
while n < 10 :
n = n + 1
if n % 2 == 0 : # 如果n是偶数，执行continue语句
continue # continue语句会直接继续下一轮循环，后续的print()语句不会执行
print(n)
TestCode：
# -*- coding: utf-8 -*-
'''
请利用循环依次对list中的每个名字打印出Hello, xxx!：
'''
L = ['Bart', 'Lisa', 'Adam']
for name in L :
print('Hello,%s!'%name)
print('''
死循环:
num = 1
while num > 0 :
num = num + 1
print(num)
''')
