Python实践操作_Python如何将文件读入列表中的？-XAMPP中文组官网

读取日志文件的Python示例，一行一行地进入列表。

# With ‘\n’, [‘1\n’, ‘2\n’, ‘3’]with open(‘/www/logs/server.log’) as f:
content = f.readlines()
# No ‘\n’, [‘1’, ‘2’, ‘3’]

with open(‘/www/logs/server.log’) as f:
content = f.read().splitlines()

1.读取文件->列表

1.1虚拟日志文件

d:\\server.log

a
b
c
d
1
2
3

包含1.2 \n

filename = “d:\\server.log”with open(filename) as f:

lines = f.readlines()
print(type(lines))

print(lines)

输出量

<class ‘list’>[‘a\n’, ‘b\n’, ‘c\n’, ‘d\n’, ‘1\n’, ‘2\n’, ‘3’]

1.3 \n排除在外

filename = “d:\\server.log”with open(filename) as f:
lines = f.read().splitlines()

print(type(lines))

print(lines)

输出量

<class ‘list’>[‘a’, ‘b’, ‘c’, ‘d’, ‘1’, ‘2’, ‘3’]
