Python Numbers
Understanding Numbers in Python (了解Python中的数字)
Python is a high-level, interpreted programming language that is widely used for various applications, including web development, machine learning, data analysis, and more. In this article, we’ll take a closer look at the various types of numbers in Python and how to use them effectively. (Python是一种高级的解释性编程语言,广泛用于各种应用程序,包括Web开发、机器学习、数据分析等。在本文中,我们将仔细研究Python中的各种类型的数字以及如何有效地使用它们。)
Integer Numbers
Integer Numbers (仅限整数)
Integers are whole numbers that can be positive, negative, or zero. In Python, integers are represented by the int data type. Here are some examples of integers in Python:
x = 10
y = -5
z = 0
You can perform various arithmetic operations with integers in Python, such as addition, subtraction, multiplication, division, and more. Here’s an example of how you can perform these operations in Python:
a = 5
b = 3
# Addition
c = a + b
print(c) # 8
# Subtraction
c = a - b
print(c) # 2
# Multiplication
c = a * b
print(c) # 15
# Division
c = a / b
print(c) # 1.6666666666666667
Float Numbers
Float Numbers (浮点数)
Float numbers, also known as floating-point numbers, are numbers that have decimal points. In Python, float numbers are represented by the float data type. Here are some examples of float numbers in Python:
x = 10.5
y = -5.2
z = 0.0
Just like integers, you can perform various arithmetic operations with float numbers in Python. However, it’s important to note that float numbers have limited precision, so the result of some operations may not be exactly as expected. (就像整数一样,您可以在Python中对浮点数执行各种算术运算。但是,需要注意的是,浮点数精度有限,因此某些操作的结果可能不完全符合预期。)
a = 5.5
b = 3.5
# Addition
c = a + b
print(c) # 9.0
# Subtraction
c = a - b
print(c) # 2.0
# Multiplication
c = a * b
print(c) # 19.25
# Division
c = a / b
print(c) # 1.5714285714285714
Complex Numbers
Complex Numbers (复数)
Complex numbers are numbers that have both real and imaginary parts. In Python, complex numbers are represented by the complex data type and are denoted by the letter j or J. Here are some examples of complex numbers in Python:
x = 10 + 5j
y = -5 + 3j
z = 0 + 0j
Just like integers and float numbers, you can perform various arithmetic operations with complex numbers in Python. Here’s an example of how you can perform these operations in Python:
a = 5 + 2j
b = 3 + 4j
# Addition
c = a + b
print(c) # (8+6j)
# Subtraction
c = a - b
print(c) # (2-2j)
# Multiplication
c = a * b
print(c) # (1+20j)
# Division
c = a / b
print(c) # (0.6-0.4j)
