在Python中读取txt文件,你可以使用以下几种方法:
1. 使用`open()`函数和`read()`方法:
```python
with open('file.txt', 'r', encoding='utf-8') as file:
content = file.read()
print(content)
2. 使用`with`语句和`read()`方法:
```python
with open('file.txt', 'r', encoding='utf-8') as file:
content = file.read()
print(content)
3. 使用`with`语句和`readlines()`方法:
```python
with open('file.txt', 'r', encoding='utf-8') as file:
lines = file.readlines()
for line in lines:
print(line, end='')
4. 使用`with`语句和逐行读取(`readline()`方法):
```python
with open('file.txt', 'r', encoding='utf-8') as file:
line = file.readline()
while line:
print(line.strip(), end='')
line = file.readline()
5. 使用`with`语句和迭代器逐行读取:
```python
with open('file.txt', 'r', encoding='utf-8') as file:
for line in file:
print(line.strip())
请确保指定正确的文件路径和编码方式,以便正确读取文件内容。如果文件不存在或不可读,将会抛出异常。
你还需要注意,使用`with`语句可以自动关闭文件,无需手动调用`close()`方法。
