1. At least 1 letter between [a-z] 
2. At least 1 number between [0-9] 
1. At least 1 letter between [A-Z] 
3. At least 1 character from [$#@] 
4. Minimum length of transaction password: 6 
5. Maximum length of transaction password: 12

19. You are required to write a program to sort the (name, age, height) tuples by ascending order where name is string, 
age and height are numbers. The tuples are input by console. The sort criteria is: 
1: Sort based on name; 
2: Then sort based on age; 
3: Then sort by score. 

The priority is that name > age > score.
If the following tuples are given as input to the program: 
Tom,19,80 
John,20,90 
Jony,17,91 
Jony,17,93 
Json,21,85

    tem=(name,age,score)
    det=det+(tem,)
print(det)
a=sorted(det,key=itemgetter(0,1,2))     #(0=name , 1=age ,2=score)
print(a,end=',')
