Python Type Conversion

Introduction

In the midst of the scorching Saharan sands lies one of the ancient world's most enigmatic wonders: the Great Pyramid of Giza. Within its labyrinthine chambers, scrolls of knowledge await discovery by those savvy enough to decipher their secrets. You are Akhmenrah, an esteemed Egyptian scholar, adept in the mystical arts and sciences. Your goal: to decode a series of numeric inscriptions that are believed to unlock the paths to hidden chambers.

As you traverse through the dimly lit passages, it becomes evident that the numeric inscriptions are not in a format that your ancient tools can interpret. You must convert these enigmatic numbers from one type to another, utilizing a mystical artifact recently uncovered: the Python of Transformation.

Your task is to master the Python's power of type conversion, allowing you to transmute strings into numbers, integers into floats, and unleash the arcane energies needed to access the pyramid's core. Only by successfully harnessing this power can you achieve your goal and reveal the pyramid's true secrets.

Converting String to Integer

In this step, you will encounter a numeric inscription on a wall, represented as a string. To unlock the mechanism in front of you, you must convert the string to an integer using Python.

Open the file /home/labex/project/convert_string_to_int.py and write your Python code.

## convert_string_to_int.py

## The numeric inscription is represented as a string
inscription = "42"

## Convert the string to an integer
inscription_as_int = int(inscription)

## Print the result to verify that the conversion is successful
print(f"Value: {inscription_as_int}, Type: {type(inscription_as_int)}")

Execute the script in the terminal to attempt the conversion:

python /home/labex/project/convert_string_to_int.py

The information below should be displayed on your terminal:

Value: 42, Type: <class 'int'>

The result means the conversion is successful, and you can proceed to the next challenge.

Converting Integer to Float

Your journey continues. You now stand before a scale that requires a precise weight to balance. The inscription shows an integer, but the scale demands a float.

Open the file /home/labex/project/convert_int_to_float.py and write the code to convert an integer to a float.

## convert_int_to_float.py

## The weight required by the scale is an integer
required_weight = 7

## Convert the integer to a float
required_weight_as_float = float(required_weight)

## Print the result to confirm the conversion
print(f"Value: {required_weight_as_float}, Type: {type(required_weight_as_float)}")

Run the script in your terminal:

python /home/labex/project/convert_int_to_float.py

The information below should be displayed on your terminal:

Value: 7.0, Type: <class 'float'>

The result confirms the successful conversion, and the scale balances, allowing you to progress deeper into the pyramid.

Summary

In this lab, we embarked on an adventurous journey into an ancient pyramid, assuming the role of a mystical scholar faced with numeric riddles. Through hands-on experience, we delved into the practical aspect of Python's type conversion abilities. Our excursion helped us understand how to decipher strings into integers and integers into floats, a process that mirrors the flexibility required in real-world programming tasks. The imaginative approach to learning Python's type conversion has allowed us to gain more than just knowledge; we have acquired a sense of wonder and excitement in solving the unknown, a trait every programmer should aspire to embrace.
