For most Python learners, the core knowledge has basically been mastered, but “what is learned from books is shallow; to truly understand, one must practice.” To fully master Python, practical application is essential.

Today, I will share with you80 Python beginner examples, all basic examples, classic and practical, with clear code that can be used directly, very suitable for learning and improvement, with wide applicability and strong practicality. Without further ado, let’s take a look!

Python Sum of Numbers

# -*- coding: UTF-8 -*-
# Filename : test.py
# author by : www.runoob.com
# User inputs numbers
num1 = input('Enter the first number: ')
num2 = input('Enter the second number: ')

# Calculate sum
sum = float(num1) + float(num2)
# Display calculation result
print('The sum of {0} and {1} is: {2}'.format(num1, num2, sum))

The output of the above code is:

Enter the first number: 1.5
Enter the second number: 2.5
The sum of 1.5 and 2.5 is: 4.0

Python Random Number Generation

# -*- coding: UTF-8 -*-
# Filename : test.py
# author by : www.runoob.com
# Generate a random number between 0 and 9
# Import random module
import random
print(random.randint(0,9))
The output of the above code is:
4
In this example, we used the randint() function from the random module to generate a random number, which returns different numbers (0 to 9) each time you execute it. The syntax of this function is:
random.randint(a,b)

Python Output Prime Numbers in a Specified Range

# Output prime numbers in a specified range
# Take input from the user
lower = int(input("Enter the minimum value of the range: "))
upper = int(input("Enter the maximum value of the range: "))
for num in range(lower,upper + 1):
# Prime numbers are greater than 1
if num > 1:
for i in range(2,num):
if (num % i) == 0:
break
else:
print(num)
The output of the above program is:
$ python3 test.py
Enter the minimum value of the range: 1
Enter the maximum value of the range: 100

Python Calculate Days in Each Month

#!/usr/bin/python3
# author by : www.runoob.com
import calendar
monthRange = calendar.monthrange(2016,9)
print(monthRange)
The output of the above code is:
(3, 30)
The output is a tuple, where the first element corresponds to the first day of the queried month (0-6), and the second element is the number of days in that month. The output of the example indicates that the first day of September 2016 was a Thursday and that month had a total of 30 days.

Python Clear a List

RUNOOB = [6, 0, 4, 1]
print('Before clearing:', RUNOOB)
RUNOOB.clear()
print('After clearing:', RUNOOB)
The output of the above example is:
Before clearing: [6, 0, 4, 1]
After clearing: []
