1. python中字符串与数组的转换方法

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

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


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

a=list('xyz')

2. Python怎么将数字数组转为字符数组

用map函数

文档


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中字符串与数组的转换方法是什么

Python实现字符串与数组相互转换功能，具体如下：

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

5. python如何将数组转化成字符串

#数组为list，使用join函数
"".join(list)

6. python数组转换为字符串

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

祝你成功。

7. 在Python中，如何将一个字符串数组转换成整

Python实现字符串与数组相互转换功能，具体如下：

1、字符串转数组：

Python(英语发音:/ˈpaɪθən/), 是一种面向对象、解释型计算机程序设计语言。

8. Python中怎么把list转换为字符串

List中存的是字符串复的时候，制一般是通过join()函数去转换：

例 ：
dataList = ['1', '2', '3', '4' ]

str1 = “ ， ” + join(dataList )

print (dataList)

结果：
a b c d

(8)python数组转化为字符串扩展阅读

关于join()函数：

join()是一个字符串方法，它返回被子字符串连接的字符串。

参数：The join() method takes join()方法需要可迭代的元素来一次返回它的一个成员，比如列表，元组，字符串，字典和集合

返回值：join()方法返回一个被子字符串连接的字符串。

Type Error: 如果这个可迭代元素包含任何不是字符串的值，join()函数就会抛出TypeError。
