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.

"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())name = "Python"
message = 'Hello World'
1. Basic Syntax
Strings can be created using single or double quotes.
name = "Alex"
city = 'Mumbai'
Both are valid strings.
2. Access Characters using Indexing
Each character has an index starting from 0.
text = "Python"
print(text[0])
print(text[3])
Output:
P
h
Negative indexing starts from the end.
print(text[-1])
Output:
n
3. String Slicing
Extract part of a string using slicing.
text = "Python"
print(text[0:3])
print(text[2:6])
Output:
Pyt
thon
4. String Length
Use len() to find the number of characters.
text = "Python"
print(len(text))
Output:
6
5. Convert Case
text = "Python Programming"
print(text.upper())
print(text.lower())
print(text.title())
Output:
PYTHON PROGRAMMING
python programming
Python Programming
6. Remove Spaces
Use strip() to remove leading and trailing spaces.
text = " Python "
print(text.strip())
Output:
Python
7. Replace Text
text = "I love Java"
print(text.replace("Java", "Python"))
Output:
I love Python
8. Split a String
Convert a string into a list.
text = "Python SQL Excel"
print(text.split())
Output:
['Python', 'SQL', 'Excel']
9. Join Strings
Join list elements into a single string.
words = ["Python", "SQL", "Excel"]
print(" | ".join(words))
Output:
Python | SQL | Excel
10. Check String Methods
text = "Python"
print(text.startswith("Py"))
print(text.endswith("on"))
print("th" in text)
Output:
True
True
True
11. String Concatenation
Combine multiple strings using +.
first = "Hello"
second = "World"
print(first + " " + second)
Output:
Hello World
12. f-Strings Recommended
The easiest way to format strings.
name = "Alex"
age = 25
print(f"My name is {name} and I am {age} years old.")
Output:
My name is Alex and I am 25 years old.
Note: f-Strings are faster and more readable than string concatenation.
13. Practice Examples
Reverse a string
text = "Python"
print(text[::-1])
Output:
nohtyP
Count occurrences
text = "banana"
print(text.count("a"))
Output:
3
Find character position
text = "Python"
print(text.find("t"))
Output:
2
Check if string contains a word
text = "I am learning Python"
print("Python" in text)
Output:
True
Note: Strings are one of the most frequently used data types in Python, especially in web development, automation, and data analysis.
💬 Tap ❤️ if this helped you learn Python faster!class Person:
def __init__(self, person_first_name, person_last_name, person_age):
self.person_first_name = person_first_name
self.person_last_name = person_last_name
self.person_age = person_age
This is good:
class Person:
def __init__(self, first_name, last_name, age):
self.first_name = first_name
self.last_name = last_name
self.age = age.dropna(), .fillna() functions to do this easily.
4. What are list comprehensions and how are they useful?
Concise syntax to create lists from iterables using a single readable line, often replacing loops for cleaner and faster code.
Example: [x**2 for x in range(5)] → ``
5. Explain Pandas DataFrame and Series.
⦁ Series: 1D labeled array, like a column.
⦁ DataFrame: 2D labeled data structure with rows and columns, like a spreadsheet.
6. How do you read data from different file formats (CSV, Excel, JSON) in Python?
Using Pandas:
⦁ CSV: pd.read_csv('file.csv')
⦁ Excel: pd.read_excel('file.xlsx')
⦁ JSON: pd.read_json('file.json')
7. What is the difference between Python’s append() and extend() methods?
⦁ append() adds its argument as a single element to the end of a list.
⦁ extend() iterates over its argument adding each element to the list.
8. How do you filter rows in a Pandas DataFrame?
Using boolean indexing:
df[df['column'] > value] filters rows where ‘column’ is greater than value.
9. Explain the use of groupby() in Pandas with an example.
groupby() splits data into groups based on column(s), then you can apply aggregation.
Example: df.groupby('category')['sales'].sum() gives total sales per category.
10. What are lambda functions and how are they used?
Anonymous, inline functions defined with lambda keyword. Used for quick, throwaway functions without formally defining with def.
Example: df['new'] = df['col'].apply(lambda x: x*2)
