Question 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
Explanation:
S2 which is nana is in bananamania hence it is a substring of s1.
Example 2:
Input:
aabbcc
abc
output:
False
Explanation:
String s1 does not contain string s2 hence the answer is false.
Solution:
def subStr(s1,s2):
if s2 in s1:
return True
else:
return False

Question 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}
Solution:
def mergeDic(d1, d2):
d3 = {}
for key,value in d1.items():
d3[key] = value
for key,value in d2.items():
if key not in d3.keys():
d3[key] = value
return d3These are answers of The Joy of Computing using Python Assignment 9 Answers
Question 3
Take an integer N as an input, print all the indexes of numbers in that integer from left to right.
Input:
122345
Output:
1 0
2 1 2
3 3
4 4
5 5
Explanation:
Given integer 122345. Now printing indexes of numbers from left to right.
First number is 1 and its index is 0 therefore
1 0
Second and third number is 2 and its index is 1,2 therefore
2 1 2
and so on…
Solution:
n = int(input())
n = str(n)
d = {}
for i in range(len(n)):
if n[i] not in d.keys():
d[n[i]] = [i]
else:
d[n[i]].append(i)
for key, value in d.items():
print(key, end= ' ')
for i in value:
print(i, end= ' ')
