Question

1. Write a Python program, with comments, to do the following:                       
   1. Ask the user to enter a string with at least 7 characters. Assume user will enter a valid string.
   2. Assign the string to a variable str1 and print str1.
   3. In a loop do the following:
      1. Update the value of str1 so that the first character from the current value of str1 is removed and added to the end.
      2. Print the updated str1.

      The loop should continue until updated value of str1 is the same as the initial value.

Answer 1

# Write a Python program, with comments, to do the following:
# Ask the user to enter a string with at least 7 characters. Assume user will enter a valid string.
str1 = input("Enter a string with at least 7 characters: ")
# Assign the string to a variable str1 and print str1.
print(str1)

initial_value = str1
# In a loop do the following:
# Update the value of str1 so that the first character from the current value of str1 is removed and added to the end.
str1 = str1[1:] + str1[0]
while str1 != initial_value:
    print(str1)
    str1 = str1[1:] + str1[0]
# Print the updated str1.
print(str1)
