您也可以在NumPy中使用loadtxt命令。这比genfromttxt检查的条件更少，因此可能更快。

import numpy
data = numpy.loadtxt(filename, delimiter="\n")

f = open("your_file.txt",'r')
out = f.readlines() # will append in the list out

现在，变量out是您想要的列表（数组）。您可以选择：

for line in out:
    print (line)

Or:

for line in f:
    print (line)

你会得到同样的结果。

您也可以在NumPy中使用loadtxt命令。这比genfromttxt检查的条件更少，因此可能更快。

import numpy
data = numpy.loadtxt(filename, delimiter="\n")

如果要包含以下内容：

with open(fname) as f:
    content = f.readlines()

如果不希望包含：

with open(fname) as f:
    content = f.read().splitlines()

这里还有一个选项，对文件使用列表理解；

lines = [line.rstrip() for line in open('file.txt')]

这应该是更有效的方法，因为大部分工作都是在Python解释器内完成的。

具有文本文件内容：

line 1
line 2
line 3

我们可以在上面txt的同一目录中使用此Python脚本

>>> with open("myfile.txt", encoding="utf-8") as file:
...     x = [l.rstrip("\n") for l in file]
>>> x
['line 1','line 2','line 3']

使用追加：

x = []
with open("myfile.txt") as file:
    for l in file:
        x.append(l.strip())

Or:

>>> x = open("myfile.txt").read().splitlines()
>>> x
['line 1', 'line 2', 'line 3']

Or:

>>> x = open("myfile.txt").readlines()
>>> x
['linea 1\n', 'line 2\n', 'line 3\n']

Or:

def print_output(lines_in_textfile):
    print("lines_in_textfile =", lines_in_textfile)

y = [x.rstrip() for x in open("001.txt")]
print_output(y)

with open('001.txt', 'r', encoding='utf-8') as file:
    file = file.read().splitlines()
    print_output(file)

with open('001.txt', 'r', encoding='utf-8') as file:
    file = [x.rstrip("\n") for x in file]
    print_output(file)

输出：

lines_in_textfile = ['line 1', 'line 2', 'line 3']
lines_in_textfile = ['line 1', 'line 2', 'line 3']
lines_in_textfile = ['line 1', 'line 2', 'line 3']
