在Python中,读取文本内容的方法有以下几种:
- 使用open()函数打开文件并读取内容:
with open('file.txt', 'r') as file:
content = file.read()
print(content)
- 逐行读取文件内容:
with open('file.txt', 'r') as file:
for line in file:
print(line)
- 读取指定行数的内容:
n = 5
with open('file.txt', 'r') as file:
for i in range(n):
line = file.readline()
print(line)
- 读取所有行并存储在列表中:
with open('file.txt', 'r') as file:
lines = file.readlines()
for line in lines:
print(line)
- 使用readline()方法逐行读取文件内容:
with open('file.txt', 'r') as file:
line = file.readline()
while line:
print(line)
line = file.readline()
这些是常用的读取文本内容的方法,根据具体需求选择合适的方法进行操作。
