在Python中逐行读取文件到数组的元素中
这个问题在这里已经有了答案:
testsite_array = []
with open('topsites.txt') as my_file:
for line in my_file:
testsite_array.append(line)
这是可能的,因为Python允许你直接迭代文件。
或者,更直接的方法,使用f.readlines()
:
with open('topsites.txt') as my_file:
testsite_array = my_file.readlines()
只需打开文件并使用readlines()
函数即可:
with open('topsites.txt') as file:
array = file.readlines()
在python中,你可以使用文件对象的readlines
方法。
with open('topsites.txt') as f:
testsite_array=f.readlines()
或者简单地使用list
,这与使用readlines
相同,但唯一的区别是我们可以将可选大小参数传递给readlines
:
with open('topsites.txt') as f:
testsite_array=list(f)
帮助file.readlines
:
In [46]: file.readlines?
Type: method_descriptor
String Form:<method 'readlines' of 'file' objects>
Namespace: Python builtin
Docstring:
readlines([size]) -> list of strings, each a line from the file.
Call readline() repeatedly and return a list of the lines so read.
The optional size argument, if given, is an approximate bound on the
total number of bytes in the lines returned.
