Question

我一直在尝试打印我在第一行打开的整个txt。前3个方法不打印整个列表，最后一个方法确实如此，但我不知道如何格式化它以使其行中的每个元素分离。

myList = open("LIST.txt","r").readlines()
#print(*myList, sep='\n')
#for elem in myList:
       # print (elem) 
#print ('\n'.join(myList))
print(myList[0:])

Answer 1

所有这些方法似乎都打印出所有行：

>>> my_list = open("list.txt").readlines()
>>> for elem in my_list:
...     print (elem)
...
First line

Second line

Third line

>>> my_list = open("list.txt").readlines()
>>> for elem in my_list:
...     print (elem)
...
First line

Second line

Third line

>>> print ('\n'.join(my_list))
First line

Second line

Third line

>>> print (''.join(my_list))
First line
Second line
Third line

>>> print(my_list[:])
['First line\n', 'Second line\n', 'Third line\n']

如果myList[0:]有效，您可以使用加入：''.join(myList[0:])。但是，如果您将线路重新组合在一起，则可能只需要read而不是readlines：

>>> print(open("list.txt").read())
First line
Second line
Third line

打印整个列表不会显示txt
