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
