We teased this last lecture — now we cover it properly
The messy way:
name = "Allah"
age = 22
print("My name is " + name + " and I am " + str(age) + " years old")
The clean way with f-strings:
name = "Allah"
age = 22
print(f"My name is {name} and I am {age} years old")
Just put f before the opening quote and wrap variables in curly braces
You can even do math inside:
price = 100
discount = 20
print(f"Final price: {price - discount}") # Final price: 80
From now on always use f-strings — forget the + method

📌 String Methods
Python gives you built in tools to work with strings
You use them with a dot after the variable
You will use these constantly when building bots
Bots deal with text all day — these are your best friends
Python gives you built in tools to work with strings
You use them with a dot after the variable
name = " allah "
print(name.upper()) # ALLAH
print(name.lower()) # allah
print(name.strip()) # allah — removes extra spaces
print(name.strip().title()) # Allah — capitalizes first letter
message = "Welcome to the channel"
print(message.replace("channel", "group")) # Welcome to the group
print(message.split(" ")) # ['Welcome', 'to', 'the', 'channel']
print(len(message)) # 22
email = "allahlovesram69@gmail.com"
print(email.startswith("allah")) # True
print(email.endswith(".com")) # True
print("gmail" in email) # True
You will use these constantly when building bots
Bots deal with text all day — these are your best friends
input() lets the user type something and your code responds
name = input("What is your name? ")
print(f"Hello {name}!")Run this and type your name — your code just talked back to you
Important — input() always gives you a string
Even if the user types a number you get it as text
So if you need to do math with it, convert it first:
age = int(input("How old are you? "))
print(f"In 10 years you will be {age + 10}")Please open Telegram to view this post

name = input("Enter your name: ").strip().title()
age = int(input("Enter your age: "))
city = input("Enter your city: ").strip()
print(f"Name : {name}")
print(f"Age : {age}")
print(f"City : {city}")
print(f"In 5 years you will be {age + 5}")
print(f"Your name has {len(name)} letters")Notice line 1 — we take input, strip spaces, and capitalize all in one line
This is how real clean code looks

Build a personal info card generator
Ask the user for name, age, city and hobby then print a formatted card:
name = input("Name: ").strip().title()
age = int(input("Age: "))
city = input("City: ").strip().title()
hobby = input("Hobby: ").strip().lower()
print("====================")
print(f" Name : {name}")
print(f" Age : {age}")
print(f" City : {city}")
print(f" Hobby : {hobby}")
print(f" Name length: {len(name)} letters")
print("====================")Screenshot your output
Bonus — add one more input of your choice

So far your code runs top to bottom and does the same thing every time
No decisions, no logic — just straight execution
This lecture changes that
Conditionals let your code make decisions
Do this IF something is true — do that if it is not
This is the moment your code starts feeling like an actual program
This lecture covers:

An if statement runs a block of code only when a condition is true
If the condition is false — it skips that block entirely
age = 20
if age >= 18:
print("You are an adult")
Two things to never forget:
Indentation is not optional in Python
It is literally how Python knows what belongs inside the if block
Miss it and your code breaks

else runs when the if condition is false:
age = 15
if age >= 18:
print("You are an adult")
else:
print("You are a minor")
elif checks multiple conditions in order:
score = 75
if score >= 90:
print("Grade: A")
elif score >= 80:
print("Grade: B")
elif score >= 70:
print("Grade: C")
elif score >= 60:
print("Grade: D")
else:
print("Grade: F")
Python checks from top to bottom
The moment one is true it runs that block and skips everything else

and — both conditions must be true:
age = 25
has_id = True
if age >= 18 and has_id:
print("Access granted")
else:
print("Access denied")
or — at least one must be true:
is_admin = False
is_owner = True
if is_admin or is_owner:
print("You can edit this")
not — flips the condition:
is_banned = False
if not is_banned:
print("Welcome back")
You will use these constantly in bots
Things like — if user is admin AND message is a command — do this

correct_password = "python123"
username = input("Enter username: ").strip().lower()
password = input("Enter password: ").strip()
if username == "admin" and password == correct_password:
print("Welcome back Admin!")
elif username == "admin" and password != correct_password:
print("Wrong password")
else:
print(f"User {username} not found")
Notice how we combined everything from the last 4 lectures
Variables, strings, input, f-strings, and now conditionals
This is how real programs are built — piece by piece

Build a number guessing hint program:
secret = 42
guess = int(input("Guess the number: "))
if guess == secret:
print("Correct!")
elif guess > secret:
print(f"Too high — you were off by {guess - secret}")
else:
print(f"Too low — you were off by {secret - guess}")
This is the base — now make it your own
Change the number, add more messages, make it interesting
Screenshot your output
Bonus — add a check: if the guess is within 5 of the secret, print "So close!"

So far your code runs once and stops
What if you need to do something 100 times?
You are not going to write 100 lines
That is where loops come in
A loop runs a block of code over and over until you tell it to stop

A while loop keeps running as long as a condition is true
The moment it becomes false — the loop stops
count = 1
while count <= 5:
print(f"Count: {count}")
count += 1
print("Done")
Output:
Count: 1
Count: 2
Count: 3
Count: 4
Count: 5
Done
count += 1 means count = count + 1
We increase count each time so the loop eventually stops
If you forget to update count the loop runs forever
This is called an infinite loop — press Ctrl+C to stop it

A for loop repeats for each item in a sequence
It is cleaner and safer than while for most situations
fruits = ["apple", "banana", "mango"]
for fruit in fruits:
print(fruit)
Output:
apple
banana
mango
You can also loop over a string — it goes letter by letter:
for letter in "Python":
print(letter)
