我需要创建代码，允许您检查您输入的坐标是否位于某个区域内。到目前为止，我有这个：

import random
import math
import pylab
import numpy    
pylab.close("all")                                                      #All import statements
x = [(random.randint(-50,50)) for i in range(10)]               #Creating list of x coordinates
y = [(random.randint(-50,50)) for j in range(10)]               #Creating list of y coordinates
array=zip(x,y)                                                          #Creating an array by combining the x and y coordinates
print array             

counter = 0                                 #Start of 1c, resetting counter
for i, j in array:                              #Telling what to inspect
        if 35**2 <= (i**2+j**2) <= 65**2:                   #Conditions for the coordinates to fall within 15 pixels of a circle with radius 50
                counter+= 1                         #If conditions met then add 1 to counter
n=(1.0*counter/7000)*100                            #Calculating percentage of coordinates in the region
print "on average", n, "% of the locations in the array fall in this region"    #Print result, end of part 1c


name = raw_input('type a coordinate location: ')                #Start of 1d, python input result
for i, j in name:
    if i in name in array:   
        if 35**2 <= (i**2+j**2) <= 65**2:
            print "warning, your chosen location falls near the edge of the circle"
    else:
         print "coordinate does not exist"

但目前我收到一条错误消息，说“需要超过 1 个值才能解包”，指的是“name = raw_input('type a coordinate location:')' 行。我究竟做错了什么？

名称是一个字符串。你不能使用

for i, j in name:

您需要先将其分解为值，然后创建一个元组。

也许是这样的：

n = (name.split(',')[0],name.split(',')[1]) - 假设坐标由 ',' 分隔

"raw_input" 返回一个字符串。您需要 split() 它并将数字转换为整数
