例如,当从文件中读取数据时,通常以 bytes 形式存储;而在进行文本处理时,需要将其转换为 string 以便于操作。 3.1 文件读取示例 下面是一个读取文件并将其内容作为 string 处理的示例: # 打开一个二进制文件并读取withopen('example.bin','rb')asfile:byte_content=file.read()# 以二进制模式读取文件# 将读取...

The most straightforward way to convert bytes to a string is using thedecode()method on the byte object (or the byte string). This method requires specifying the character encoding used. Note: Strings do not have an associated binary encoding and bytes do not have an associated text encoding....
Alternatively, the first character of the format string can be used to indicate the byte order, size and alignment of the packed data, according to the following table: If the first character is not one of these,'@'is assumed. Format characters have the following meaning; the conversion betw...
This is a good option if you need to dynamically evaluate Python expressions. When you pass a string argument toeval(), it compiles it into bytecode and evaluates it as a Python expression. Essentially, theeval()function allows you to convert strings to integers. Let's look at some ...
