# 🐍 TryHackMe: Python Basics – Walkthrough

This document contains a complete walkthrough of the Python Basics room on TryHackMe. It's designed for beginners and covers essential Python concepts like printing, arithmetic, variables, conditionals, loops, functions, and file handling.

📌 Basic Printing

To begin with, we print a simple string to the console:

print("Hello World")

Flag: THM{PRINT_STATEMENTS}

---

➗ Arithmetic Operations

Performing different arithmetic operations in Python:

# Addition
print(21 + 43)  # 64

# Subtraction
print(142 - 52)  # 90

# Multiplication
print(10 * 342)  # 3420

# Exponentiation (5 squared)
print(5**2)  # 25

Flags:

• Addition: THM{ADDITI0N}
• Subtraction: THM{SUBTRCT}
• Multiplication: THM{MULTIPLICATION_PYTHON}
• Exponentiation: THM{EXP0N3NT_POWER}

---

🧮 Variables

We assign and update variables:

height = 200
height = height + 50
print(height)  # 250

Flag: THM{VARIABL3S}

🚚 Conditional Logic – Shipping Calculator

Simple conditional logic based on cost:

customer_basket_cost = 34
customer_basket_weight = 44

if customer_basket_cost > 100:
    print("free shipping")
else:
    shipping = 1.20 * customer_basket_weight
    total = customer_basket_cost + shipping
    print(total)  # 86.8

Flag: THM{IF_STATEMENT_SHOPPING}

If we increase the basket cost to trigger free shipping:

customer_basket_cost = 101
customer_basket_weight = 44

if customer_basket_cost > 100:
    print(customer_basket_cost)  # 101
else:
    shipping = 1.20 * customer_basket_weight
    total = customer_basket_cost + shipping
    print(total)

Flag: THM{MY_FIRST_APP}

---

🔁 Loops

Loop from 0 to 50 using a for loop:

for i in range(51):
    print(i)

Flag: THM{L00PS_WHILE_FOR}

---

💰 Functions & Conditions – Bitcoin Alert

Define a function and use it to trigger alerts based on value:

def bitcoinToUSD(bitcoin_amount, bitcoin_value_usd):
    total = bitcoin_amount * bitcoin_value_usd
    return total

flag = bitcoinToUSD(1.2, 4000)

if flag < 30000:
    print("Alert!!!")
elif flag == 30000:
    print("It's worth 30k bro")
else:
    print("It's worth more than 30k bro")

Flag: THM{BITC0IN_INVESTOR}

---

📂 File Handling

Read content from a file:

file = open("flag.txt", "r")
print(file.read())

Flag: THM{F1LE_R3AD}
