Mastering Python Lists Series: Exploring Key Concepts and Use Cases
Topic 1: Creating and Adding Elements to a List
In this tutorial, we dive into the basics of Python lists, starting with creating an empty list and dynamically adding elements using the append method. Learn about the object-oriented nature of Python, classes, methods, and how to use references to manipulate lists effectively.
Sample Program
x = []
x.append(10)
x.append(20)
x.append(30)
x.append(40)
x.append(50)
print(x)
Topic 2: Count Method for Lists
Explore the powerful count method in Python lists. See how to count the occurrences of specific elements in a list and gain insights into handling data efficiently.
Sample Program
x = [1, 2, 3, 4, 5, 6, 7, 8, 1, 2, 3, 4, 5, 6, 7, 8, 1, 2, 3, 4, 5, 6, 7, 8]
occurs = x.count(1)
print(occurs) # Output: 3
Topic 3: Insert Method and Exploring API
Delve into the insert method, comparing it with append. Understand the importance of declaring an index and value for insert to add elements at specific positions in a list.
Sample Program
x = list()
x.insert(0, 1)
x.insert(1, 2)
x.insert(2, 3)
x.insert(3, 4)
x.insert(4, 5)
print(x)
Topic 4: Real-world Use Case - Sorting Employee Salaries
Solve a practical problem by sorting employee salaries into buckets based on experience levels. Get hands-on experience with Python lists in a real-world scenario.
Sample Program
emp_salaries = [10000, 4000, 6000, 20000, 19500, 164000, 30000, 40000, 50000, 60000, 70000, 80000]
fresh_list = []
exp_list = []
Validation and Print Data
#Please symbol for lessthan.
for sal in emp_salaries:
if sal lessthan= 30000:
fresh_list.append(sal)
else:
exp_list.append(sal)
print("The fresher list ", fresh_list)
print("The experienced list ", exp_list)
