🚀 Day 61/150 – Find String Length Without len() in Python

Sometimes it’s useful to understand how Python counts characters internally.
Instead of using len(), we can count each character manually.

Example:
"python" → Length = 6

Let’s explore different ways 👇

🔹 Method 1 – Using for Loop

text = "python" count = 0 for ch in text: count += 1 print("Length:", count)

🔹 Method 2 – Using while Loop

text = "python" count = 0 while text[count:]: count += 1 print("Length:", count)

🔹 Method 3 – Taking User Input

text = input("Enter a string: ") count = 0 for ch in text: count += 1 print("Length:", count)

🔹 Method 4 – Using Recursion

def string_length(s): if s == "": return 0 return 1 + string_length(s[1:]) print(string_length("python"))

💡 Key Takeaways

• Strings are iterable, so you can count characters one by one
• for loop is the easiest manual way
• while and recursion help understand string behavior
• Great exercise for learning loops and indexing
