How to convert list to string in python

To convert a list into a string in python, first convert all the elements in the list into str type, and then use Python's built-in string function join to connect the elements in the list.

The examples are as follows:

>>> list1=['ak','uk',4]
>>> list2=[str(i) for i in list1] #使用列表推导式把列表中的单个元素全部转化为str类型
>>> list2 #查看转化后的列表
['ak', 'uk', '4']
>>> list3=' '.join(list2) #把列表中的元素放在空串中，元素间用空格隔开
>>> list3 #查看生成的长串
'ak uk 4'

Join function introduction:

The join() function in Python is used to connect the elements in the sequence with specified characters to generate a new String.

join() function syntax:

str.join(sequence)

Parameters: sequence -- the sequence of elements to be connected.

Return value: Returns a new string generated by concatenating elements in the sequence by the specified character.

The following examples show how to use join():

str = "-";
seq = ("a", "b", "c"); # 字符串序列
print str.join( seq );

The output results are as follows:

a-b-c
