Yuqori yangilanish chastotasi (oxirgi ma’lumot 06 Oktabr, 2026 da olingan) sababli kanal doimo dolzarb va katta qamrovli bo‘lib qoladi. Analitika auditoriya kontent bilan faol hamkorlik qilishini, uni Texnologiyalar & Aralashmalar toifasidagi muhim ta’sir nuqtasiga aylantirishini ko‘rsatadi.
num = 10
print(num / 0)
❌ Output → ZeroDivisionError
💡 Without exception handling, the program stops immediately when an error occurs.
1. Basic Syntax:
› Use try and except to handle errors.
try:
num = 10 / 0
except ZeroDivisionError:
print("Cannot divide by zero")
✔ Output → Cannot divide by zero
2. Catch Any Exception:
Use Exception to handle all types of errors.
try:
number = int("Hello")
except Exception:
print("Something went wrong")
✔ Output → Something went wrong
3. Catch Multiple Exceptions:
try:
num = int(input("Enter a number: "))
print(10 / num)
except ValueError:
print("Invalid number")
except ZeroDivisionError:
print("Cannot divide by zero")
💡 Different errors can be handled separately.
4. Using else:
The else block runs only if no exception occurs.
try:
num = 10 / 2
except ZeroDivisionError:
print("Error")
else:
print("Division Successful")
✔ Output → Division Successful
5. Using finally:
The finally block always executes, whether an exception occurs or not.
try:
print(10 / 2)
except ZeroDivisionError:
print("Error")
finally:
print("Program Finished")
✔ Output →
5.0
Program Finished
💡 Commonly used to close files or database connections.
6. Using raise:
Manually raise an exception.
age = -5
if age < 0:
raise ValueError("Age cannot be negative")
✔ Output → ValueError: Age cannot be negative
7. Get the Error Message:
try:
print(10 / 0)
except Exception as e:
print(e)
✔ Output → division by zero
💡 e stores the actual error message.
8. Nested Exception Handling:
try:
try:
print(10 / 0)
except ZeroDivisionError:
print("Inner Exception")
except:
print("Outer Exception")
✔ Output → Inner Exception
9. Common Python Exceptions:
✔ ZeroDivisionError → Dividing by zero: 10 / 0
✔ ValueError → Invalid value: int("Hello")
✔ TypeError → Invalid data type: 10 + "20"
✔ IndexError → Invalid list index:
nums = [1, 2]
print(nums[5])
✔ KeyError → Missing dictionary key:
student = {"name": "Alex"}
print(student["age"])
✔ FileNotFoundError → File doesn't exist: open("data.txt")
10. Practice Examples:
✔ Handle invalid input
try:
age = int(input("Enter age: "))
print(age)
except ValueError:
print("Please enter a valid number")
✔ Handle list index error
try:
nums = [10, 20]
print(nums[5])
except IndexError:
print("Index out of range")
✔ Handle dictionary key error
try:
student = {"name": "Alex"}
print(student["age"])
except KeyError:
print("Key not found")
💡 Exception handling makes your programs more reliable by preventing unexpected crashes and providing meaningful error messages.

✔ Add a new key
student["country"] = "India"
print(student)
✔ Update a value
student["age"] = 23
print(student)
💡 Dictionaries are one of the most powerful data structures in Python and are widely used to store structured data like JSON, APIs, and database records.

1.32 ₽ · /balance_helpstudent = {
"name": "Alex",
"age": 22,
"city": "Mumbai"
}
1. Basic Syntax:
› Dictionaries use curly braces {}.
› Each item consists of a key: value pair.
person = {
"name": "John",
"age": 25
}
💡 Keys must be unique, but values can be duplicated.
2. Access Dictionary Values:
Access values using their keys.
student = {
"name": "Alex",
"age": 22
}
print(student["name"])
print(student["age"])
✔ Output
Alex
22
3. Using get() Method:
Safely access a value without getting an error if the key doesn't exist.
student = {
"name": "Alex",
"age": 22
}
print(student.get("name"))
✔ Output
Alex
💡 If the key doesn't exist, get() returns None by default.
4. Change Dictionary Values:
student = {
"name": "Alex",
"age": 22
}
student["age"] = 23
print(student)
✔ Output
{'name': 'Alex', 'age': 23}
5. Add New Items:
student = {
"name": "Alex"
}
student["city"] = "Mumbai"
print(student)
✔ Output
{'name': 'Alex', 'city': 'Mumbai'}
6. Remove Items:
Using pop()
student.pop("age")
Using del
del student["city"]
Remove all items
student.clear()
7. Dictionary Length:
student = {
"name": "Alex",
"age": 22
}
print(len(student))
✔ Output
2
8. Loop Through a Dictionary:
Loop through keys
for key in student:
print(key)
✔ Output
name
age
Loop through values
for value in student.values():
print(value)
✔ Output
Alex
22
Loop through key-value pairs
for key, value in student.items():
print(key, value)
✔ Output
name Alex
age 22
9. Check if a Key Exists:
student = {
"name": "Alex",
"age": 22
}
print("name" in student)
✔ Output
True
10. Common Dictionary Methods:
✔ keys() → Returns all keys
print(student.keys())
✔ values() → Returns all values
print(student.values())
✔ items() → Returns key-value pairs
print(student.items())
✔ update() → Updates dictionary
student.update({"age": 24})
✔ Output
{'name': 'Alex', 'age': 24}
11. Nested Dictionaries:
students = {
"student1": {
"name": "Alex",
"age": 22
},
"student2": {
"name": "John",
"age": 25
}
}
print(students["student1"]["name"])
✔ Output
Alex
12. Practice Examples:
✔ Print all keys
student = {
"name": "Alex",
"age": 22
}
print(student.keys())
