[英]How to store_true and store value in a mutual exclusive group in argparse?
I want to do something like this:我想做这样的事情:
usage: myprogpy [-su | -re STRING | -reg]
How do I check which of the arguments were given ( su
, re
, reg
), and in the case of re
, obtain the given string?我如何检查给出了哪些参数( su
、 re
、 reg
),并且在re
的情况下,获取给定的字符串?
ap = argparse.ArgumentParser(prog="myprog.py")
method_group = ap.add_mutually_exclusive_group()
method_group.add_argument('-su', '--speedup', action='store_true', dest='method')
method_group.add_argument('-re', '--relative', action='store_true', dest='method')
method_group.add_argument('-reg', '--regular', action='store_true', dest='method')
args = ap.parse_args()
if args.method == "speedup":
speedup()
elif args.method == "relative":
relative(string_value) # How do I get the string value???
elif args.method == "regular":
regular()
Is it possible to get assign true/false
value in method
, as well as storing the string in a different variable?是否可以在method
分配true/false
值,以及将字符串存储在不同的变量中? Is there another way?还有其他方法吗?
Use the (default) 'store'
and 'store_const'
actions, not 'store_true'
.使用(默认) 'store'
和'store_const'
操作,而不是'store_true'
。
ap = argparse.ArgumentParser(prog="myprog.py")
method_group = ap.add_mutually_exclusive_group()
method_group.add_argument('-su', '--speedup',
action='store_const',
const='speedup',
dest='method')
method_group.add_argument('-re', '--relative',
dest='method')
method_group.add_argument('-reg', '--regular',
action='store_const',
const='regular',
dest='method')
args = ap.parse_args()
if args.method == "speedup":
speedup()
elif args.method == "regular":
regular()
elif args.method is not None:
relative(args.method)
