In Python, when you write a code, the interpreter needs to understand what each part of your code does. Tokens are the smallest units of code that have a specific purpose or meaning. Each token, like a keyword, variable name, or number, has a role in telling the computer what to do....
When working with statements like these, keep in mind that the Python interpreter does the calculation and then regards the statement as the result of the calculation. In other words, Python replaces the original statement with actual values. With more programming experience, you’ll start looking...

一个for 语句在Python语法中是这么定义的: for_stmt: 'for' exprlist 'in' testlist ':' suite ['else' ':' suite] exprlist 是一组被赋值的变量. 这就等于说这组变量在每次迭代开始的时候都会执行一次 {exprlist} = {next_value}。 下面这个例子很好的解释了上面想要表达的意思: for i in range(...
