name = "Alice"
age = 25
height = 5.6
is_student = True

print(type(name), type(age), type(height), type(is_student))

age = 20
if age >= 18:
    print("Adult")
else:
    print("Minor")

for i in range(1, 11):
    if i % 2 == 0:
        print(i)

def multiply(a, b):
    return a * b

print(multiply(3, 4))

fruits = ["apple", "banana", "cherry"]
print(fruits[1])

student = {"name": "John", "score": 90}
print(student["name"])

import numpy as np
array = np.array([1, 2, 3, 4])
print(array * 3)

import pandas as pd
data = {"Name": ["Alice", "Bob"], "Score": [85, 90]}
df = pd.DataFrame(data)
print(df)

numbers = [1, 2, 3, 4, 5]
squares = [x**2 for x in numbers]
print(squares)
