defmyint(string):returnint(string)parse("I am {:myint}","I am 27",dict(myint=myint))type(_[0]) 利用它,我们可以定制很多的功能,比如我想把匹配的字符串弄成全大写 defshouty(string):returnstring.upper()parse('{:shouty} world','hello world',dict(shouty=shouty)) 10 总结一下 parse 库在字...
当前传入的参数只能是int、str、float、comlex类型,不能为函数,这有点不方便,但我们通过下面的列子给点启发: import argparse p = argparse.ArgumentParser(description = 'For function use') #定义必须输入一个int型参数 p.add_argument('Intergers',help = 'one or more intergers is need',metavar = 'N'...
