python读取txt, 准备工作

It seems that there was an error in reading the file. This might be due to the file not existing at the specified path.

I will try to read the file again, but this time I'll use a different file name, assuming it's a common one. Let's try with 'example.txt'.It appears that there is still an issue with reading the file. This could be due to the file not existing in the specified location or due to other reasons.

If you have a specific text file that you would like to read, please provide the file name or the content of the file, and I will attempt to read it for you.

Python读取txt文件详解

在数据处理和编程范畴,文本文件(txt)是一种十分常见的数据存储格局。Python作为一种功能强大的编程言语,供给了多种办法来读取和操作txt文件。本文将具体介绍Python中读取txt文件的办法,包含根本操作和高档技巧。

准备工作

在进行txt文件读取之前,保证你的Python环境现已搭建好。你能够运用PyCharm、VSCode等IDE来编写和运转Python代码。

翻开文件

在Python中,你能够运用`open()`函数来翻开一个txt文件。以下是一个简略的示例:

```python

with open('example.txt', 'r') as file:

content = file.read()

print(content)

在这个比如中,`'example.txt'`是你要读取的文件名,`'r'`表明以只读形式翻开文件。`with`句子保证文件在操作完成后会被正确封闭。

按行读取

假如你只需求读取文件的一行,能够运用`readline()`办法:

```python

with open('example.txt', 'r') as file:

line = file.readline()

print(line, end='') end='' 避免主动增加换行符

逐行读取

假如你想逐行读取文件,能够运用`for`循环结合`readline()`办法:

```python

with open('example.txt', 'r') as file:

for line in file:

print(line, end='')

读取一切行到列表

假如你想要将文件的一切行读取到一个列表中,能够运用`readlines()`办法:

```python

with open('example.txt', 'r') as file:

lines = file.readlines()

for line in lines:

print(line, end='')

读取特定格局数据

关于结构化的数据,如CSV文件,你能够运用`csv`模块来读取:

```python

import csv

with open('data.csv', 'r') as csvfile:

reader = csv.reader(csvfile)

for row in reader:

print(row)

读取二进制文件

假如你需求读取二进制文件,能够运用`'rb'`形式翻开文件:

```python

with open('binaryfile.bin', 'rb') as file:

binary_data = file.read()

print(binary_data)

反常处理

在文件操作中,可能会遇到文件不存在或无法读取的状况。运用`try...except`句子能够处理这些反常:

```python

try:

with open('nonexistent.txt', 'r') as file:

content = file.read()

print(content)

except FileNotFoundError:

print(\
