Question

Write a program for a basic string extraction.

The program should:

• Display a message stating its goal
• Prompt the user to enter any input
• Extract only the string characters from the input
• Display the extraction in lowercase
• For example, for the input "But, why?!?" the output should be but why

Remember:

• Do not use more advanced functions than needed.
• Make sure to include comments that explain all your steps (starts with #).
• Run the program a few times to make sure it executes and meets all the requirements

Answer 1

CODE IN PYTHON:

#taking a string as input from the user
str = raw_input("Enter a string:")
output = ""
#extracting only string
for ch in str:
if((ch >= 'a' and ch <='z') or (ch >= 'A' and ch <='Z') or (ch >= '0' and ch<='9') or ch==' '):
output += ch
#displaying the output
print(output)
