Reminder

1, the number of digits in the number of calculations of a document

a = 0
with open("number.txt", "r", encoding="utf8") as f:
    ret = f.readlines()
    for item in ret:
        print(item, type(item))
        for i in item:
            if i.isdigit():
                a+=1
    print(a)

 2, * kwargs use

DEF FUNC (** kwargs):
     for I in kwargs: # I is a key-value pair for each key obtained 

        Print (I, kwargs [I]) 


FUNC (OK =. 1, 2 = Yes, = NO. 3 ) 

# parsing 
Print ( I) 
OK 
Yes 
NO 


Print (kwargs) 
{ ' OK ' :. 1, ' Yes ' : 2, ' NO ' :. 3 } 
{ ' OK ' :. 1, ' Yes ' : 2, ' NO ' :. 3 } 
{ 'OK ' :. 1, ' Yes ' : 2, ' NO ' :. 3 } 

so the result is 
OK . 1 
Yes 2 
NO . 3
