Building coding skills by solving Python Code Examples is very important. Python is rapidly growing especially in the last few years with advancement in technologies like Artificial intelligence and machine learning.
The ability of Python Programming Language to integrate with these technologies and help in building sustainable and helpful software solutions is the major reason for its advancement in a few years.
Let us know some of the cool Python Code Examples to help you solve complex problems within seconds.
Python Code Examples with Explanation
The Python Programming language consists of a variety of libraries and frameworks for various complex tasks in the world of programming. Knowing these frameworks will help you become a better programmer in the future. Let us start with some cold python code examples below.
1. Tuples
Tuple is an in-built data type of Python programming language which is used to store different collections of data. Tuples are immutable objects unlike lists which cannot be changed or modified once defined.
They are more efficient in memory storage than other languages’ data types like dictionaries, sets, lists, etc. Tuple is enclosed within round brackets (“ ”)

| # Creating a tuple
tuple_example = (1, 2, 3) print(tuple_example) # Output: (1, 2, 3) print (tuple_example[1]) #Output: ‘2’ print (tuple_example[0]) #Output: ‘1’ |
2. Slicing
Slicing in Python is used to access a content specific part within a sequence, such as list, tuple, or string. The syntax for slicing contains three important parameters i,e. start, stop, and step
sequence[start:stop:step]
The given example below represents a list of various options that can be performed.
| my_list = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
# Slicing with only start, stop slice1 = my_list[2:6] # Slicing with start, stop, and step slice2 = my_list[1:8:2] # Slicing from the start to a specific position slice3 = my_list[:5] # Slicing from a specific position to the end slice4 = my_list[5:]
# Slicing with a negative step to reverse the list slice5 = my_list[::-1] print(“slice1:”, slice1) # Output: [2, 3, 4, 5] print(“slice2:”, slice2) # Output: [1, 3, 5, 7] print(“slice3:”, slice3) # Output: [0, 1, 2, 3, 4] print(“slice4:”, slice4) print(“slice5:”, slice5) # Output: [9, 8, 7, 6, 5, 4, 3, 2, 1, 0] |
Now, let us check python coding examples of a tuple where there are three elements in a tuple making it a nested tuple.
| nested_tuple = (1, (2, 3), (4, 5, 6))
print(nested_tuple) # Output: (1, (2, 3), (4, 5, 6)) print(nested_tuple[1][1]) # Output: 3 |
We can return our tuple as a function, let us learn how to return multiple values from a function as a tuple.
| # Function returning a tuple
def get_student_info(): name = “John” grade = “A” age = 20 return name, grade, age # Returns a tuple student_info = get_student_info() print(student_info) # Output: (‘John’, ‘A’, 20) |
3. Using Alias
Python supports Classes and objects and you can easily assign an object to an identifier and when you assign one identifier variable to another identifier variable both of them reference to the same object.
| import math as m
print(m.sqrt(16)) # Uses `m` as an alias for `math` |
5. ‘Not’ Operator
The Not operator in Python is a logical operator used to return true if the expression is false. It inverts the truth value of the expression and objects in python.

| x = True
y = False print(not x) print(not y) |
6. End Parameter in Print Function
The end parameter is used to specify the end subject when displayed using a print statement. The default value of end is “/n” which tells Python to get to a new line. Check Python code examples below in the table
| print(“Hello”, end=” “)
print(“World!”) |
7. Merge Dictionaries
You can merge to different dictionaries using the bitwise OR operator or simple Update() method in Python. Check Python code examples below in the table
| dict1 = {“name”: “Alice”, “age”: 25}
dict2 = {“city”: “New York”, “job”: “Engineer”} dict1.update(dict2) print(dict1) |
8. Ternary Operator/ Conditional Expressions
The ternary operator (also called a conditional expression) allows you to evaluate an expression based on a condition. It’s a concise alternative to a traditional if-else statement. Here, if the condition is True, “John” is assigned to name; otherwise, “Doe” would be assigned. Check the Python code examples below in the table
| condition = True
name = “John” if condition else “Doe” print(name) |
Example 9 Remove Duplicates From Lists
You can easily remove duplicates from Python code by converting the list to a set, we automatically remove any duplicate values since sets do not allow duplicates. Then, we convert the set back to a list to maintain the list data type.
| a = [1, 1, 2, 3, 4, 5, 5, 5, 6, 7, 2, 2]
print(list(set(a))) |
Example 10: The Setdefault Method
The setdefault() method checks whether a key exists in the dictionary. If the key doesn’t exist, it adds the key with a specified default value (in this case, 0). Then, the count for each word is incremented. Check Python code examples below in the table
| import print
text = “It’s the first of April. It’s still cold in the UK. But I’m going to the museum so it should be a wonderful day” counts = {} for word in text.split(): counts.setdefault(word, 0) counts[word] += 1 pprint.pprint(counts) |
| {‘April.’: 1, ‘But’: 1, “I’m”: 1, “It’s”: 2, ‘UK.’: 1, ‘a’: 1, ‘be’: 1, ‘cold’: 1, ‘day’: 1, ‘first’: 1, ‘going’: 1, ‘in’: 1, ‘it’: 1, ‘museum’: 1, ‘of’: 1, ‘should’: 1, ‘so’: 1, ‘still’: 1, ‘the’: 3, ‘to’: 1, ‘wonderful’: 1} |
Popular Python Coding Examples For Beginners
Let us learn some of the popular python problems frequently asked during many interviews and in university exams of Python. Let us check some of the frequent python coding examples.

Given below are some simple arithmetic operations in Python such as Addition, subtraction, division, multiplication for beginners.
| a = 10
b = 5 print(“Addition:”, a + b) print(“Subtraction:”, a – b) print(“Multiplication:”, a * b) print(“Division:”, a / b) |
Example 2: Using If-Else Conditions
Check using Python code example, whether a person is eligible to vote based on age criteria.
| age = 20
if age >= 18: print(“Eligible to vote”) else: print(“Not eligible to vote”) |
Example 3: List Operations
The example below demonstrates adding and removing items in a list, showing basic list manipulations.
| fruits = [“apple”, “banana”, “cherry”]
fruits.append(“orange”) fruits.remove(“banana”) print(fruits) |
Example 4: Dictionary Lookup
You can easily access values in a dictionary by key, showing how to use both [ ] notation and get method.

return f”Hello, {name}!” print(greet(“Ankit”)) |
Example 6: Lambda Function
The Lamda Function calculates the square of a given number
| square = lambda x: x * x
print(square(5)) |
