Python Project: Manipulating User Input Text

Level: Beginner

Apr 08, 2025

Project Overview 💡

In this project, you’ll practice basic string manipulations in Python. You’ll ask the user for their full name, then perform various operations like converting to uppercase/lowercase, removing spaces, counting characters, and reversing the name.

Challenge Yourself! 🚀

Before checking the solution, try to solve the task of this project on your own!

Task:

Write a Python program that:

Accepts a user's full name as input
Prints the name in uppercase and lowercase
Removes spaces and counts the characters
Reverses the name

Expected Output: Here is how the program would work. The program asks the user to enter their name (e.g., user enters “John Smith”) and then prints out the output.

Step-by-Step Guide

Step 1️⃣: Get User Input

Ask the user to input their full name.

Place this code in line 1-2:

# Get the user's full name
full_name = input("Please enter your full name: ")

Step 2️⃣: Display the Name in Uppercase

Convert the string to uppercase using .upper().

Place this code in line 4-5:

# Display the name in uppercase
print("Your name in uppercase:", full_name.upper())

Step 3️⃣: Display the Name in Lowercase

Convert the string to lowercase using .lower().

Place this code in line 7-8:

# Display the name in lowercase
print("Your name in lowercase:", full_name.lower())

Step 4️⃣: Remove Spaces and Count Characters

Remove all spaces using .replace() and count the characters using len().

Place this code in lines 10-12:

# Remove spaces and count the total number of characters
name_no_spaces = full_name.replace(" ", "")
print("Total number of characters (excluding spaces):", len(name_no_spaces))

Step 5️⃣: Reverse the Name

Use slicing to reverse the string.

Place this code in lines 14-16:

# Reverse the name
reversed_name = full_name[::-1]
print("Your name reversed:", reversed_name)

Complete Code 🧨

# Get the user's full name
full_name = input("Please enter your full name: ")

# Display the name in uppercase
print("Your name in uppercase:", full_name.upper())

# Display the name in lowercase
print("Your name in lowercase:", full_name.lower())

# Remove spaces and count the total number of characters
name_no_spaces = full_name.replace(" ", "")
print("Total number of characters (excluding spaces):", len(name_no_spaces))

# Reverse the name
reversed_name = full_name[::-1]
print("Your name reversed:", reversed_name)

Alternative Solution

Here's a version using a function to group all string manipulations:

def analyze_name(name):
    print("Your name in uppercase:", name.upper())
    print("Your name in lowercase:", name.lower())
    print("Total number of characters (excluding spaces):", len(name.replace(" ", "")))
    print("Your name reversed:", name[::-1])

full_name = input("Please enter your full name: ")
analyze_name(full_name)

Comparison

The original version does each operation directly in sequence.
The alternative version groups logic inside a function — better for reuse and organization. Using functions is better for more complex programs. For our program, the original version is optimal.
