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]
