Week 9 Programming Assignment 1 :-
Given two string s1 and s2, write a function subStr which accepts two parameters s1 and s2 and will return True if a s2 is a substring of s1 otherwise return False. A substring is a is a contiguous sequence of characters within a string.
Input:
bananamania
nana
Output:
True
Week 9 Programming Assignment 1
def subStr(s1,s2): return(s2 in s1)
Week 9 Programming Assignment 2 :-
Given two dictionaries d1 and d2, write a function mergeDic that accepts two dictionaries d1 and d2 and return a new dictionary by merging d1 and d2.
Note: Contents of d1 should be appear before contents of d2 in the new dictionary and in same order. In case of duplicate value retain the value present in d1.
Input:
{1: 1, 2: 2}
{3: 3, 4: 4}
output:
{1: 1, 2: 2, 3: 3, 4: 4}
Week 9 Programming Assignment 2
def mergeDic(d1,d2):
for i in d2.keys():
if i not in d1.keys():
d1[i]=d2[i]
return(d1)
