Why is this failing on number 29

!/bin/python3

import math import os import random import re import sys

if name == 'main': n = int(input().strip())

if n in range(1, 101): if n % 2==0 and n in range(6, 21): print("Weird") elif n % 2==0 and n in range(2, 6) or n > 20: print("Not Weird") elif n % 2==1: print("Weird")

n = int(input()) student_marks = {} for _ in range(n): data = input().split() name = data[0] scores = list(map(float, data[1:])) student_marks[name] = scores query_name = input() average_marks = sum(student_marks[query_name]) / len(student_marks[query_name])

print(f"{average_marks:.2f}")

This fails on the numbers 18 and 20 in here, but runs correctly locally on python 3.12.7

n = int(input().strip())
    if n % 2 != 0:
        message = 'Weird'
    elif n in range(2,6):
        message = 'Not Weird'
    elif n in range(6-21):
        message = 'Weird'
    else:
        message = 'Not Weird'
    print(message)

For Python3 Platform

n = int(input())

if(n % 2 != 0):
    print("Weird")
else:
    if(2 <= n <= 5):
        print("Not Weird")
    elif(6 <= n <= 20):
        print("Weird")
    else:
        print("Not Weird")

n = int(input().strip())

print("Not Weird" if n % 2 == 0 and (n in range(2,6) or n > 20) else "Weird")
