If you’re learning Python…
you’ve probably done these already 👇
1️⃣ Using = Instead of == ❌
if x = 5: # ❌ Error
👉
= is assignment 👉
== is comparison 2️⃣ Not Understanding Mutable Objects 🔗
a = [1, 2]
b = a
b.append(3)
print(a)
Output: [1, 2, 3]
👉 Both changed 😳
👉 Because they point to SAME object
3️⃣ Forgetting Indentation ⚠️
if True:
print("Hello") # ❌
👉 Python depends on indentation
👉 One mistake → code breaks
4️⃣ Using is Instead of == 🤯
a = 1000
b = 1000
print(a is b)
👉 Might return False
👉 Because
is checks memory, not value 5️⃣ Modifying List While Looping 🔥
nums = [1, 2, 3]
for x in nums:
nums.remove(x)
👉 Leads to unexpected bugs
👉 Loop skips elements
💡 Key Idea
Most bugs in Python
come from misunderstanding how it works internally 🚀
