easy📝 Syntax Q12 of 15
Step-by-Step Solution
Solution:
Step 1: Check the order of arguments in
The correct order ispolyfitpolyfit(x, y, degree).Step 2: Confirm the degree argument is positional, not keyword
polyfitexpects degree as the third positional argument, not as a keyword.Final Answer:
coeffs = scipy.polyfit(x, y, 3) -> Option BQuick Check:
Correct syntax = coeffs = scipy.polyfit(x, y, 3) [OK]
Quick Trick: Remember: polyfit(x, y, degree) with degree as positional [OK]
Common Mistakes:
- Swapping x and y arguments
- Omitting the degree argument
- Using degree as a keyword argument
