                [TOC] ## Python3中字符串、列表、數組的轉換方法 1、list轉換為str 當list中存放的數據是字符串時,一般是通過str中的join函數進行轉換: ``` list = ['a','b','c','d'] str1 = ''.join(list) str2 = ' '.join(list) str3 = '.'.join(list) print(str1) print(str2) print(str3) ----------------------------------- 輸出結果: abcd a b c d a.b.c.d ``` 但是當list中存放的數據是整型數據或者數字的話,需要先將數據轉換為字符串再進行轉換: ``` list = [1, 2, 3, 4] str1 = ''.join([str(x) for x in list]) str2 = ' '.join([str(x) for x in list]) str3 = '.'.join([str(x) for x in list]) print(str1) print(str2) print(str3) ----------------------------------- 輸出結果: 1234 1 2 3 4 1.2.3.4 ```
