Python Numbers, Type Conversion and Mathematics In this article, you'll learn about the different numbers used in Python, how to convert from one data type to the other, and the mathematical operations supported in Python. Table of Contents Number Data Type in Python Type Conversion Python Decim...
Below is the table, showing the major differences between thedecode()andstr()for conversion of bytes to string: MethodCharacter encodingFlexibility decode()Can specify any character encodingMore flexible str()Limited to standard encodings such as ASCII, UTF-8, UTF-16Less flexible ...

The decode() method is used in the script to convert the bytes objects into string data. The same encoding is used at the time of conversion. #!/usr/bin/env python3 # Take a string value text = input("Enter any text:\n") # Initialize bytearray object with string and encoding byte...
However, we can include the optional errors argument to handle any errors. The default value for the errors parameter is "strict", which raises an error for invalid characters. The .decode() method can be called with errors="ignore" to ignore all invalid characters: text = data.decode("asc...

# Converting bytes to string while ignoring errors string_data = byte_data_invalid.decode('utf-8', errors='ignore') print(string_data) You’ll now get the following output without any errors: Output >>> Hello, World! Replacing Errors ...
调用bytes()函数(其实是bytes的构造方法)将字符串按指定字符集转换成字节串,如果不指定字符集,默认使用UTF-8字符集。 调用字符串本身的encode()方法将字符串按指定字符集转换成字节串,如果不指定字符集,默认使用UTF-8字符集。 # 创建一个空的bytesb1 =bytes()# 创建一个空的bytes值b2 =b''# 通过b前缀指定...
