从理论上讲,将来的实现也可以使用决策树并行处理case子句,而不是逐个测试它们。 向后兼容 This PEP is fully backwards compatible: the match and case keywords are proposed to be (and stay!) soft keywords, so their use as variable, function, class, module or attribute names is not impeded at ...
# match,从起始位置开始匹配,匹配成功返回一个对象,未匹配成功返回None match(pattern, string, flags=0) # pattern: 正则模型 # string : 要匹配的字符串 # falgs : 匹配模式 X VERBOSE Ignore whitespace and comments for nicer looking RE's. I IGNORECASE Perform case-insensitive matching. M MULTILINE...

Through a process calledrehashing, pyenv maintains shims in that directory to match every Python command across every installed version of Python—python,pip, and so on. Shims are lightweight executables that simply pass your command along to pyenv. So with pyenv installed, when you run, say,...
which is evaluated by replacing it with its associated value. Since it is only the value of the actual parameter that is passed, not any variable name, there isno needto have a variable name used in an actual parameter match a formal parameter name. (Here we have the value ofuserNamein...
Everything in the example is present in the same scope, and the variable e got removed due to the execution of the except clause. The same is not the case with functions that have their separate inner-scopes. The example below illustrates this: def f(x): del(x) print(x) x = 5 y...
