Lists vs Dictionaries

When working on data scraping tasks, it's essential to be familiar with core Python data structures like lists, and dictionaries, as they are key to processing and organizing the scraped data efficiently.

an_empty_list = []
an_empty_dictionary = dict()

Common List Operations

1. append()

data = []
data.append("Product A")
data.append("Product B")
print(data)  # Output: ['Product A', 'Product B']

2. extend()

data1 = ["Product A", "Product B"]
data2 = ["Product C", "Product D"]
data1.extend(data2)
print(data1)  # Output: ['Product A', 'Product B', 'Product C', 'Product D']

Common Dictionary Operations

1. get()

data = {"name": "Laptop", "price": 999.99}
product_name = data.get("name", "Unknown")
product_rating = data.get("rating", "No rating")  # Key not present, returns default
print(product_name)  # Output: Laptop
print(product_rating)  # Output: No rating

2. keys()

data = {"name": "Laptop", "price": 999.99}
keys = data.keys()
print(keys)  # Output: dict_keys(['name', 'price'])

3. values()

data = {"name": "Laptop", "price": 999.99}
values = data.values()
print(values)  # Output: dict_values(['Laptop', 999.99])

4. items()

data = {"name": "Laptop", "price": 999.99}
for key, value in data.items():
    print(f"{key}: {value}")
# Output:
# name: Laptop
# price: 999.99
