Python - Data Types as Values

You have a list of mixed numbers: nums = [1, 2.5, 3, 4.75, 5]. You want to create a new list with all numbers converted to integers by dropping decimals. Which code correctly does this?

Anew_nums = [int(n) for n in nums]

Bnew_nums = [float(n) for n in nums]

Cnew_nums = [str(int(n)) for n in nums]

Dnew_nums = [round(n) for n in nums]

Step-by-Step Solution

Solution:

Step 1: Understand the goal
We want to convert all numbers to int by dropping decimals, not rounding.
Step 2: Evaluate each option
C uses int() which drops decimals correctly. A converts to string, not int. B converts to float, not int. D rounds numbers, which changes values.
Final Answer:
new_nums = [int(n) for n in nums] -> Option A
Quick Check:
int() drops decimals, list comprehension applies to all [OK]

Quick Trick: Use int() in list comprehension to drop decimals [OK]

Common Mistakes:

MISTAKES

Using round() instead of int()
Converting to string instead of int
Using float() which keeps decimals
