Question

3. Write a Python program to ask user input of a string, then ask user input of what letters they want to remove from the string. User can either put in "odd", "even" or a number "n" that is greater than 2. When user input "odd", it will remove the characters which have odd numbers in the sequence of the string. When user input "even", it will remove the characters which have even numbers in the sequence of the string. When user input "n" number, it will remove the characters which have nth numbers in the sequence of the string. Note that we are talking about the sequence of the letters, so the first letter in a string is number 1, the second is number 2, and so on.

Example:

Input string = "abcdef"

Input choice = "odd"

Output = "bdf"

Input string = "python"

Input choice = "even"

Output = "pto"

Input string = "abcdef"

Input choice = "3"

Output = "abde"

Answer 1

s=input("Enter input string:")
ch=input("Enter choice:")#read inputs from user
res=""
if ch=="odd":#if choice is odd
for i in range(1,len(s)+1):
if i%2==0:#add only even placed characters
res+=s[i-1]
  
elif ch=="even":#if choice is even
for i in range(1,len(s)+1):
if i%2!=0:#add only odd placed characters
res+=s[i-1]
else:
ch=int(ch)
for i in range(1,len(s)+1):
if i%ch!=0:#if i is not multiple of ch entered
res+=s[i-1]#append the characters
print("Output = ",res)
