Calculate Distance between Two Points using GEOPY

Calculate Distance between Two Points using GEOPY is a classic practice problem. State the rule, trace a tiny input, then code. Fibonacci: next = sum of last two. Second largest: watch duplicates. Hanoi: move n-1, biggest, n-1. Distance: sqrt((x2-x1)**2 + (y2-y1)**2).

For Calculate Distance between Two Points using GEOPY: say the output for one small n before you write the loop. That is the exam.

Exam tip

Rule + one dry-run + then code.

Example

# Calculate Distance between Two Points using GEOPY
import math
x1, y1, x2, y2 = 0, 0, 3, 4
print(math.sqrt((x2 - x1) ** 2 + (y2 - y1) ** 2))

Calculate Distance between Two Points using GEOPY — output: 5.0. 3-4-5 triangle.

Short notes

DefCalculate Distance between Two Points using GEOPY — know the rule.
RuleCalculate Distance between Two Points using GEOPY — tiny trace first.
RememberCalculate Distance between Two Points using GEOPY — edge cases (n=0, duplicates).
