因此,income < 10000的if表达式评估为False,因此块#1不会被执行。 控制权转移到下一个条件评估器:elif income < 30000。这个评估为True,因此块#2被执行,因此,Python 在整个if/elif/elif/else子句之后恢复执行(我们现在可以称之为if子句)。if子句之后只有一条指令,即print调用,它告诉我们我今年将支付3

(compared to Lisp), so it's done rarely and by specialists. The use ofexec()is frowned upon. It's easy enough to understand, but hard to get right. Python Abstract Syntax Tree (AST) manipulation is a somewhat more reliable technique, but not for the faint of heart. Python AST is ...

What is an Abstract Syntax Tree, and how is it created in Python? How does an AST help you write programs and projects that inspect and modify your Python code? This week on the show, Meredydd Luff, co-founder of Anvil, shares his PyCon talk, "Building a Python Code Completer." ...
