Passing Dictionary as a Parameter to a Function

Somnath PaulChoudhury

I usually make videos of simple and easy techniques that explains slowly in this channel. It can be a small program in Python. Normally I have posted these in some prominent pages related to CS study in CBSE class 12 exam study and preparations.

Problem Statement
==========================================================
Populate an empty dictionary students using while loop.
Add students name as key and marks obtained in a paper as related values.
Pass this dictionary as a parameter to a user defined function.
The user defined function has two lists, while traversing the dictionary
one accepts the keys and other accepts values.
The function then prints both the lists. Finally the functions prints the
list with keys in reverse order and pops all elements from the other list.

Code
=====================
students=dict()
while(True):
name=input("Enter name ")
marks=int(input("Enter marks "))
students.update({name:marks})
ans=input("Wanna cont? ")
if(ans=='n' or ans=='N'):
break


Enter name ires
Enter marks 67
Wanna cont? y
Enter name toni
Enter marks 48
Wanna cont? y
Enter name spc
Enter marks 99
Wanna cont? n
students
{'ires': 67, 'toni': 48, 'spc': 99}
def adic(a):
L1=[]
L2=[]
for i in a:
L1.append(i)
L2.append(a[i])
print(L1)
print(L2)
print(L1[::-1])
n=len(L2)
for i in range(n):
print(L2.pop(), end=" ")


adic(students)
['ires', 'toni', 'spc']
[67, 48, 99]
['spc', 'toni', 'ires']
99 48 67
