[咨询]python能不能一句话把整数数组组合成字符串？

paktc

>>> arr=[1,2,3,4,5]
>>> "".join(arr)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: sequence item 0: expected string, int found
>>>

ssfjhh

>>> arr=[1,2,3,4,5]
>>> ''.join(map(str,arr))
'12345'
>>> ''.join(i.__str__() for i in arr)
'12345'
>>> ''.join(str(i) for i in arr)
'12345'
>>> ''.join(i.__repr__() for i in arr)
'12345'
>>>

paktc

回复 2# ssfjhh
