1. python中字元串與數組的轉換方法

['x','y','z']=>'xyz'

b=''.join(['x','y','z'])


'xyz'=>['x','y','z']

a=list('xyz')

2. Python怎麼將數字數組轉為字元數組

用map函數

文檔


map(function,iterable,...)

Applyfunctionto every item ofiterableand return a list of the results. If additionaliterablearguments are passed,functionmust take that many arguments and is applied to the items from all iterables in parallel. If one iterable is shorter than another it is assumed to be extended withNoneitems. IffunctionisNone, the identity function is assumed; if there are multiple arguments,map()returns a list consisting of tuples containing the corresponding items from all iterables (a kind of transpose operation). Theiterablearguments may be a sequence or any iterable object; the result is always a list.

a=[1,2,3,4]
s=map(str,a)

3. Python中字元串與數組的轉換方法是什麼

Python實現字元串與數組相互轉換功能，具體如下：


1、字元串轉數組：專

4. python能不能一句話把整數數組組合成字元串

用map函數

a = [1,2,3,4]
s = map(str,a)

5. python如何將數組轉化成字元串

#數組為list，使用join函數
"".join(list)

6. python數組轉換為字元串

",".join(map(str,[eleforsubinsStr1foreleinsub]))
",".join(map(str,sStr1))

祝你成功。

7. 在Python中，如何將一個字元串數組轉換成整

Python實現字元串與數組相互轉換功能，具體如下：

1、字元串轉數組：

Python(英語發音:/ˈpaɪθən/), 是一種面向對象、解釋型計算機程序設計語言。

8. Python中怎麼把list轉換為字元串

List中存的是字元串復的時候，制一般是通過join()函數去轉換：

例 ：
dataList = ['1', '2', '3', '4' ]

str1 = 「 ， 」 + join(dataList )

print (dataList)

結果：
a b c d

(8)python數組轉化為字元串擴展閱讀

關於join()函數：

join()是一個字元串方法，它返回被子字元串連接的字元串。

參數：The join() method takes join()方法需要可迭代的元素來一次返回它的一個成員，比如列表，元組，字元串，字典和集合

返回值：join()方法返回一個被子字元串連接的字元串。

Type Error: 如果這個可迭代元素包含任何不是字元串的值，join()函數就會拋出TypeError。
