For instance, if you type “A1resource”, the program should display “A1ce” and if you type A1, the program should display “A1”

💻 Program Code

main.phy
----------

import sys
def main ():
main ()

TypeCast.py
-------------
def strings_onboth_ends(str):
    if len(str) < 2:
     return ""
    return str[0:2] + str[-2:]

print(strings_onboth_ends ("w3resource"))
print(strings_onboth_ends ("w3"))
print(strings_onboth_ends ("w"))

🖥 Program Output

w3ce
w3w3

📘 Explanation

🎯 How to learn from this example

First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.

🔥 Practice suggestion

Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
