📊 Auditoriya ko‘rsatkichlari va dinamika
невідомо sanasidan buyon loyiha tez o‘sib, 77 284 obunachiga ega bo‘ldi.
29 Avgust, 2026 dagi oxirgi ma’lumotlarga ko‘ra kanal barqaror faollikka ega. Oxirgi 30 kunda obunachilar soni 327 ga, so‘nggi 24 soatda esa 2 ga o‘zgardi va umumiy qamrov yuqori darajada qolmoqda.
- Tasdiqlash holati: Tasdiqlanmagan
- Jalb etish (ER): Auditoriya o‘rtacha 2.71% darajada jalb etiladi. Nashrdan keyingi dastlabki 24 soatda kontent odatda umumiy obunachilar sonining 1.11% ini tashkil etuvchi reaksiyalarni to‘playdi.
- Post qamrovi: Har bir post o‘rtacha 2 091 marta ko‘riladi; birinchi sutkada odatda 857 ta ko‘rish yig‘iladi.
- Reaksiyalar va o‘zaro ta’sir: Auditoriya faol: har bir postga o‘rtacha 4 ta reaksiya keladi.
- Tematik yo‘nalishlar: Kontent learning, accuracy, distribution, panda, dataset kabi asosiy mavzularga jamlangan.

Yuqori yangilanish chastotasi (oxirgi ma’lumot 30 Avgust, 2026 da olingan) sababli kanal doimo dolzarb va katta qamrovli bo‘lib qoladi. Analitika auditoriya kontent bilan faol hamkorlik qilishini, uni Taʼlim toifasidagi muhim ta’sir nuqtasiga aylantirishini ko‘rsatadi.
student = { "name": "Rahul", "age": 22, "course": "Data Science" }
print(student)
Output: {'name': 'Rahul', 'age': 22, 'course': 'Data Science'}
✔ Uses curly brackets {}
🔹 2. Access Dictionary Values
Use the key to access values.
student = { "name": "Rahul", "age": 22 }
print(student["name"])
Output: Rahul
🔹 3. Add New Elements
student = { "name": "Rahul", "age": 22 }
student["city"] = "Delhi"
print(student)
Output: {'name': 'Rahul', 'age': 22, 'city': 'Delhi'}
🔹 4. Modify Values
student["age"] = 23
🔹 5. Remove Elements
student.pop("age")
🔹 6. Important Dictionary Methods
⭐
✅ Get Method:
print(student.get("name"))
Output: Rahul
✅ Keys Method:
print(student.keys())
Output: dict_keys(['name', 'age'])
✅ Values Method:
print(student.values())
Output: dict_values(['Rahul', 22])
✅ Items Method:
print(student.items())
Output: dict_items([('name', 'Rahul'), ('age', 22)])
🔹 7. Loop Through Dictionary
student = { "name": "Rahul", "age": 22 }
for key, value in student.items():
print(key, value)
Output:
name Rahul
age 22
🎯 Today’s Goal
✔ Understand key–value pairs
✔ Access dictionary values
✔ Add or update data
✔ Loop through dictionary
👉 Dictionaries are widely used in APIs, JSON data, and machine learning datasets.
Double Tap ♥️ For Moreif condition:
# code
Example
age = 20
if age >= 18:
print("You can vote")
# Output: You can vote
🔹 2. if–else Statement
Used when there are two possible outcomes.
Syntax
if condition:
# code if true
else:
# code if false
Example
age = 16
if age >= 18:
print("Eligible to vote")
else:
print("Not eligible")
🔹 3. if–elif–else Statement
Used when there are multiple conditions.
Syntax
if condition1:
# code
elif condition2:
# code
else:
# code
Example
marks = 75
if marks >= 90:
print("Grade A")
elif marks >= 60:
print("Grade B")
else:
print("Grade C")
🔹 4. Nested if Statement
An if statement inside another if.
age = 20
citizen = True
if age >= 18:
if citizen:
print("Eligible to vote")
🔹 5. Short if (Ternary Operator)
age = 20
print("Adult") if age >= 18 else print("Minor")
🎯 Today’s Goal
✔ Understand if
✔ Use if–else
✔ Use elif for multiple conditions
✔ Learn nested conditions
👉 Conditional logic is used in data filtering and decision models.
Double Tap ♥️ For Moredef function_name():
# code
✅ Example
def greet():
print("Hello Deepak")
greet()
Output: Hello Deepak
🔹 3. Function with Parameters
Parameters allow input to functions.
def greet(name):
print("Hello", name)
greet("Rahul")
# Output: Hello Rahul
🔹 4. Function with Return Value (Very Important ⭐)
Instead of printing, functions can return values.
def add(a, b):
return a + b
result = add(5, 3)
print(result)
# Output: 8
👉 return sends value back.
🔹 5. Default Parameters
def greet(name="Guest"):
print("Hello", name)
greet()
greet("Amit")
🔹 6. Why Functions Matter in Data Science?
✅ Data cleaning functions
✅ Feature engineering functions
✅ Reusable ML pipelines
✅ Code organization
🎯 Today’s Goal
✔ Understand def
✔ Use parameters
✔ Use return
✔ Call functions properly
