5 Essential Python Tips Every Beginner Should Know!

Hey Everyone! If you're just getting into Python, here are five super useful tips that'll make your coding journey way smoother.

1️⃣ Clean Code Using List Comprehensions
Instead of writing a loop to perform simple list transformations, use this:

nums = [1, 2, 3, 4, 5]
squared = [x**2 for x in nums] # [1, 4, 9, 16, 25]

2️⃣ Swap Two Variables without a Temp Variable
Python makes the swap easy!

a, b = 5, 10
a, b = b, a # Now a = 10, b = 5

3️⃣ Use enumerate() Instead of range(len(.))
Instead of:

for i in range(len(my_list)):
print(i, my_list[i])

Do this:

for index, value in enumerate(my_list):
print(index, value)

4️⃣ Use zip() to Iterate Over Multiple Lists
Need to loop over two lists at once?

names = ["Alice", "Bob", "Charlie"]
scores = [85, 90, 78]

for name, score in zip(names, scores): # zip unpacks the corresponding elements from names and scores as name and score
print(f"{name} scored {score}")

5️⃣ Use get() for Safe Dictionary Access
Prevent Key Errors when you Access a dictionary:

student = {"name": "John", "age": 20}
print(student.get("grade", "N/A")) # Output: "N/A" without an error
