我需要創建代碼,它允許您檢查您輸入的座標是否位於特定區域內。到目前爲止,我有這樣的:如何檢查座標是否位於某個區域?
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"
但此刻我得到一個錯誤信息,說「需要1個多值解包」指的是「名稱=的raw_input(」鍵入一個座標位置:「)」行。我究竟做錯了什麼?
請不要使用單字母變量名稱。對於初學者來說,他們在代碼中不易辨別。有意義的名稱使代碼更易於閱讀。 當然,我可能會想到的唯一有意義的單字母變量名是x,y和z – volcano 2013-04-10 08:46:54
