Python – math.dist() 方法

Python中的数学模块包含许多数学运算，可以使用该模块轻松执行。 Python中的math.dist()方法用于计算两点 p 和 q 之间的欧几里得距离，每个点都以坐标序列（或可迭代）的形式给出。这两个点必须具有相同的尺寸。
此方法是Python 3.8 版中的新方法。

Syntax: math.dist(p, q)

Parameters:
p: A sequence or iterable of coordinates representing first point
q: A sequence or iterable of coordinates representing second point

Returns: the calculated Euclidean distance between the given points.

代码 #1：使用math.dist()方法

# Python Program to explain math.dist() method
  
# Importing math module
import math
  
# One dimensional Point
  
# Coordinate of Point P
P = 3
  
# Coordinates of point Q
Q = -8
  
# Calculate the Euclidean distance 
# between points P and Q
eDistance = math.dist([P], [Q])
print(eDistance)

输出：

11.0

代码#2：

# Python Program to explain math.dist() method
  
# Importing math module
import math
  
# Two dimensional Point
  
# Coordinates of Point P
Px = 3 
Py = 7
  
# Coordinates of point Q
Qx = -5
Qy = -9
  
# Calculate the Euclidean distance 
# between points P and Q
eDistance = math.dist([Px, Py], [Qx, Qy])
print(eDistance)
  
  
# Three-dimensional point
  
# Coordinates of Point P
P = [3, 6, 9]
  
# Coordinates of point Q
Q = [1, 0, -2] 
  
# Calculate the Euclidean distance 
# between points P and Q
eDistance = math.dist(P, Q)
print(eDistance)

输出：

17.88854381999832
12.688577540449518

代码#3：

# Python Program to explain math.dist() method
  
# Importing math module
import math
  
# n-dimensional Point
  
# Coordinates of Point P
P = [3, 9, 7, 2, 4, 5] 
  
# Coordinates of point Q
Q = [-5, -3, -9, 0, 6, 2]
  
# Calculate the Euclidean distance 
# between points P and Q
eDistance = math.dist(P, Q)
print(eDistance)
  
# Dimension of both points 
# should be the same 

输出：

21.93171219946131
