一、List转String

1、str list转 string

a_list = ["h","e","l","l","o"]print ",".join(a_list)

2、int list转 stirng

2.1 lamda

num_list = [0,1,2,3,4,5,6,7,8,9]num_list_new = [str(x) for x in num_list]print ",".join(num_list_new)

2.2 map函数

num_list = [0,1,2,3,4,5,6,7,8,9]num_list_new = map(lambda x:str(x), num_list)print ",".join(num_list_new)

二、List转List

1、int list转string list   -- 参见上一小节

num_list = [0,1,2,3,4,5,6,7,8,9]num_list_new = [str(x) for x in num_list]

 

2、string list转int list

python2 　

results = ['1', '2', '3']results = map(int, results)》》》results = [1, 2, 3]

python3

results = ['1', '2', '3']results = list(map(int, results))》》》results = [1, 2, 3]
