m="monday"
s="sunday"
def foo(**kws):
    loc = locals()#把locals()方法
    print(loc)
    print(kws) # 这样试试
    for i in kws:
        print(i,"=",kws[i])
foo(s=s)
print("********************")


# 现在的打印效果some code  monday
# 希望的打印效果 t  monday

import inspect
def foo2(s):
    arg_name = [n for n, v in inspect.currentframe().f_back.f_locals.items()
                if v is s][0]
    print(f'{arg_name} -> {s}')

foo2(m)
foo2(s)
