Python Learning Roadmap
Step 1: Learn Python syntax
Step 2: Understand variables and data types
Step 3: Learn loops and conditions
Step 4: Study functions
Step 5: Practice object-oriented programming
Step 6: Work with files

Python Calculation Example
Suppose a Python developer earns $30 per hour.
Hours worked in one week:
40 hours
Formula:
Weekly Salary = Hourly Rate × Hours Worked
Calculation:
Weekly Salary = 30 × 40
Weekly Salary = $1,200
Monthly Salary (Approximate):
$1,200 × 4 = $4,800
Yearly Salary:
$1,200 × 52 = $62,400
Python can also perform this calculation easily.
hourly_rate = 30
hours = 40
weekly_salary = hourly_rate * hours
monthly_salary = weekly_salary * 4
yearly_salary = weekly_salary * 52
print(weekly_salary)
print(monthly_salary)
print(yearly_salary)
Output:
1200
4800
62400
