Python Type Conversion Tutorial – int, float & str Explained Fast!
Assignment: Python Type Conversion
Easy Level (Beginner – Basics Practice)
1) Create a variable of type int with value 25, a float with value 10.5, and a string "Python". Print their values and types using type().
2) Take two numbers as input, add them, and print:
Their sum
The data type of the sum
3) Convert a string "45" to an integer and a string "3.14" to a float. Print their types.
4) Create a variable num = 100. Convert it into a string and concatenate it with " is my number". Print the result.
5) Take input from the user as a string, convert it to an integer, and multiply it by 10. Print the final output.
Medium Level (Concept + Logic)
6) Create a list of numbers [10, 5.5, "20", 7]. Convert all numeric strings to integers or floats, then calculate and print their sum.
7) Write a program to check the data type of each element in a list [10, "hello", 3.5, True] and print the result in the format: "Value: 10, Type: int".
8) Take three inputs from the user: one int, one float, and one string representing a number. Convert all to float and print their sum.
Hard Level (Thinking + Strong Concepts)
9) Create a mixed list [12, "30", 5.5, "Python", True, "7.2"]. Convert all elements that can be converted to numbers into floats, then print the list.
10) Write a program that:
Takes a string input
Converts it into a list of characters
Converts all numeric characters to integers
Converts it back to a string (numbers remain as digits)
Prints the final result
