 p1={'name':'Virat Kohli', 'role':'bat', 'runs':112, '4':10, '6':0, 'balls':119, 'field':0}

 bowling(p1,p2,p3,p4,p5)    #passing dict as argument

`px` is not defined in the code – Devesh Kumar Singh May 29 '19 at 07:19 — Devesh Kumar Singh, May 29 '19 at 07:19

python can not access variables the way you think it does... (with x=1 python will not be able to access p1 when you write px; px is just a new name that has not been defined yet).

what you could do is this:

def bowling(*args):
    for px in args:
        print(px.get("role"))

bowling(p1, p2, p3, p4, p5)

i.e. use a variable number of arguments *args and iterate over them. you can find more information on how to use those in the python documentation or here or here for example.
