Lists in Python

# List बनवणे
fruits = ["Apple", "Mango", "Banana", "Orange"]
numbers = [1, 2, 3, 4, 5]
mixed = [1, "hello", 3.14, True, None]  # Mixed types!

# Indexing
print(fruits[0])    # Apple
print(fruits[-1])   # Orange (last item)
print(fruits[1:3])  # ['Mango', 'Banana'] — slicing

# Length
print(len(fruits))  # 4

fruits = ["Apple", "Mango", "Banana"]

# ADD
fruits.append("Orange")    # शेवटी add करतो
fruits.insert(1, "Guava")  # index 1 वर insert करतो
print(fruits)  # ['Apple', 'Guava', 'Mango', 'Banana', 'Orange']

# REMOVE
fruits.remove("Mango")  # value by name काढतो
popped = fruits.pop()   # शेवटचा काढतो आणि return करतो
fruits.pop(0)           # index 0 चा काढतो

# CHANGE
fruits[0] = "Strawberry"  # value बदलतो

# OTHER USEFUL METHODS
nums = [3, 1, 4, 1, 5, 9, 2, 6]
nums.sort()       # ascending sort
nums.reverse()    # उलटा करतो
print(nums.count(1))  # 1 किती वेळा आहे? → 2

# Normal way
squares = []
for i in range(1, 6):
    squares.append(i * i)
print(squares)  # [1, 4, 9, 16, 25]

# List comprehension — same result, एक line!
squares = [i * i for i in range(1, 6)]
print(squares)  # [1, 4, 9, 16, 25]

# With condition — फक्त even numbers
evens = [x for x in range(1, 11) if x % 2 == 0]
print(evens)  # [2, 4, 6, 8, 10]
