本文实例讲述了python开发之for循环操作。分享给大家供大家参考，具体如下：

下面是我做的一些学习记录供大家参考：

#基本的for循环语句test_list = [2,"Jone",3,6,7,'hongten','hanyuan','good',"Tom"]#打印列表的长度print(len(test_list))#遍历列表for i in test_list: print(i)test_str = "hello,i'm hongten"print('打印字符串：' + test_str)#遍历一个字符串print('遍历一个字符串')for i in test_str: print(i)test_tuple = [("a",1),("b",2),("c",3),("d",4)]print(test_tuple)#遍历一个元组print('遍历一个元组')for (i,j) in test_tuple: print(i,j)test_dict = {'name':'hongten','age':'20','gender':'M','sports':'足球，乒乓球，游泳'}#字典迭代器for key in test_dict: print(key + ':' + test_dict[key])L1 = [1,3,5,7]L2 = [2,4,6,8]#使用zip将两个列表合并print(zip(L1,L2))for (i,j) in zip(L1,L2): print(i,j)print('#######################################################')L3 = L2[:]L3.remove(8)print('L1,L3列表为：')print(L1)print(L3)for (i,j) in zip(L1,L3): print(i,j)#可以看出来当长度不一的时候，多余的被忽略test_keys = ['name','age','gender','weight','hight']test_values = ['Hongten','20','M','55','170']#使用zip来构造一个字典print('字典中的keys：')print(test_keys)print('字典中的key对应的value：')print(test_values)print('构造字典后')test_dic = dict(zip(test_keys,test_values))for key in test_dic: print( key + ':' + test_dic[key])

运行效果：
