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']

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()

这将从文件中生成一个“数组”。

lines = tuple(open(filename, 'r'))

open返回一个可以迭代的文件。当您遍历一个文件时，您会从该文件中获取行。tuple可以使用迭代器，并从您给它的迭代器中为您实例化一个tuple实例。

如果您想从命令行或stdin读取文件，也可以使用fileinput模块：

# reader.py
import fileinput

content = []
for line in fileinput.input():
    content.append(line.strip())

fileinput.close()

将文件传递给它，如下所示：

$ python reader.py textfile.txt

    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']

使用此项：

import pandas as pd
data = pd.read_csv(filename) # You can also add parameters such as header, sep, etc.
array = data.values

data是一种数据帧类型，使用值获取ndarray。您还可以使用array.tolist（）获取列表。
