Parse Key-Value Lines

MediumPython18 min15 XP

Problem

Given text with one key=value pair per line, return a dictionary. Ignore blank lines. Strip spaces around keys and values.

Why This Matters

A lot of real scripting is turning messy text into structured data. This problem teaches careful splitting and whitespace handling.

Function Signature

def parse_settings(text):

Examples

Example 1

Input"lr = 0.1\nepochs=10\n\nmodel = linear"

Output{"lr": "0.1", "epochs": "10", "model": "linear"}

Blank lines are skipped and spaces around keys/values are removed.

Constraints

Every non-blank line contains =.
Values should remain strings.
Split on the first = only.

CodePython

def parse_settings(text):
    """
    Input example: "lr = 0.1\nepochs=10\n\nmodel = linear"
    Return: {"lr": "0.1", "epochs": "10", "model": "linear"}
    Return the value from the function so the tests can compare it. Do not print unless the prompt asks.
    """
    settings = {}
    # write your code here
    return settings

Spaces and blank line

Input"lr = 0.1\nepochs=10\n\nmodel = linear"

Expected{"lr": "0.1", "epochs": "10", "model": "linear"}

split("=", 1) avoids breaking values that may contain another equals sign.

Equals sign inside value

Input"query=a=b"

Expected{"query": "a=b"}

Only the first equals sign separates key from value.
