Week 8 Programming Assignment 1 :-
Given a Tuple T, create a function squareT that accepts one argument and returns a tuple containing similar elements given in tuple T and its sqaures in sequence.
Input:
(1,2,3)
Output :
(1,2,3,1,4,9)
Week 8 Programming Assignment 1
def squareT(T): return(T+tuple([i*i for i in T]))
Week 8 Programming Assignment 2 :-
Given a string S, write a function replaceV that accepts a string and replace the occurrences of 3 consecutive vowels with _ in that string. Make sure to return and print the answer string.
Input:
aaahellooo
Output:
_hell_
Week 8 Programming Assignment 2
def isvowel(ch):
v = 'AEIOUaeiou'
if ch in v:
return True
else:
return False
def replaceV(s):
n = len(s)
ans = ''
i=0
while(i<n-2):
if isvowel(s[i]) and isvowel(s[i+1]) and isvowel(s[i+2]):
ans = ans+'_'
i = i+3
else:
ans = ans+s[i]
i = i+1
return ans+s[i:]
S = input()
print(replaceV(S),end='')
