When processing text data, we often encounter the problem of garbled characters. Garbled characters refer to the abnormal display of characters caused by the character encoding conversion process. Python provides some methods to encode and decode strings to help us solve the problem of garbled characters. This article will introduce how to use Python for string encoding and decoding, and provide corresponding source code examples.
- String encoding
Before processing strings, you first need to understand the concept of character encoding. Character encoding is the process of converting characters into a sequence of bytes. Common character encodings include ASCII, UTF-8, GBK, etc. In Python, the default encoding for strings is UTF-8.
If we want to convert a string into a sequence of bytes, we can use the encode() method of the string. This method accepts a parameter to specify the encoding method. Here's an example:
text = "你好，世界！"
encoded_text = text.encode("UTF-8")
print(encoded_text)
Running the above code, the output is:
b'\xe4\xbd\xa0\xe5\xa5\xb
