Entry-level code examples for understanding Python programming
Python is an easy-to-learn, yet powerful programming language. For beginners, it is very important to understand the introductory code examples of Python programming. This article will provide you with some concrete code examples to help you get started quickly.
- Print Hello World
print("Hello World")This is the simplest code example in Python. The print() function is used to output the specified content to the console.
- Calculate the sum of two numbers
a = 5
b = 10
c = a + b
print("兩個(gè)數(shù)字的和為：", c)In this example, we define two variables a and b, and add them and assign them to the variable c. Then use the print() function to output the results to the console.
- Judge digital parity
num = int(input("請(qǐng)輸入一個(gè)整數(shù)："))
if num % 2 == 0:
print("這個(gè)數(shù)字是偶數(shù)")
else:
print("這個(gè)數(shù)字是奇數(shù)")In this example, we use the input() function to get the integer entered by the user and store it in the variable num. Then use the if statement to determine whether num is an even number. If so, output "This number is even." Otherwise, output "This number is odd."
- Use a loop to print numbers
for i in range(1, 11):
print(i)In this example, we use a for loop to iterate through the numbers in a range and output each number using the print() function to the console.
- List operations
fruits = ["apple", "banana", "cherry"]
print("水果列表：", fruits)
fruits.append("orange")
print("添加一個(gè)水果后的列表：", fruits)
fruits.remove("banana")
print("刪除一個(gè)水果后的列表：", fruits)
if "apple" in fruits:
print("列表中包含蘋果")
else:
print("列表中不包含蘋果")This example shows common operations on lists. We first create a list of fruits, then use the append() function to add an element to the list, and use the remove() function to remove an element from the list. Then use an if statement to determine whether the list contains the specified element.
Hope the above code examples can help you get started with Python programming. Through actual code examples, you can better understand the basic syntax and common operations of the Python language, laying a solid foundation for further learning and developing Python projects.

AssertionError: How to resolve Python assertion errors?
Jun 25, 2023 pm 11:07 PM
Assertions in Python are a useful tool for programmers to debug their code. It is used to verify that the internal state of the program meets expectations and raise an assertion error (AssertionError) when these conditions are false. During the development process, assertions are used during testing and debugging to check whether the status of the code matches the expected results. This article will discuss the causes, solutions, and how to correctly use assertions in your code. Cause of assertion error Assertion error pass

Usage of sqrt() function in Python
Feb 21, 2024 pm 03:09 PM
Usage and code examples of the sqrt() function in Python 1. Function and introduction of the sqrt() function In Python programming, the sqrt() function is a function in the math module, and its function is to calculate the square root of a number. The square root means that a number multiplied by itself equals the square of the number, that is, x*x=n, then x is the square root of n. The sqrt() function can be used in the program to calculate the square root. 2. How to use the sqrt() function in Python, sq
