Length and direction cosines of lines - tarikrr - Nov-14-2019
Good day,
First time posting, and new to python
I'm trying to get the user to input the number of lines he wants, then input the coordinates for the line ends for each line
say the user enters the number of lines: 10
then how can I prompt him to input the x y coordinates for each line end for each line (10 times for example)
then store those coordinates to do some operations on it like finding each line length and finding each line direction cosines?
thank you!

The first part of getting the input is rather easy. Here's the code to do so
numberOfLines = input('Enter the number of lines you want: ')
alphabetList = ['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'J', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y' ,'Z']
lineDict = {}
for x in range(0, int(numberOfLines)):
count = 1
while x > 25:
x -= 25
count += 1
if count > 1:
label = f'{count}{alphabetList[x]}'
else:
label = f'{alphabetList[x]}'
lineDict.update({label : input(f'Enter the x and y coordinates for line "{label}" separated by commas, for example: 3, -1\n').split(',')})Here my output from testing itOutput:Enter the number of lines you want: 10
Enter the x and y coordinates for line "A" separated by commas, for example: 3, -1
10, 1
Enter the x and y coordinates for line "B" separated by commas, for example: 3, -1
2, 9
Enter the x and y coordinates for line "C" separated by commas, for example: 3, -1
0, -35
Enter the x and y coordinates for line "D" separated by commas, for example: 3, -1
-1010, 1
Enter the x and y coordinates for line "E" separated by commas, for example: 3, -1
3, -3i
Enter the x and y coordinates for line "F" separated by commas, for example: 3, -1
1, 9
Enter the x and y coordinates for line "G" separated by commas, for example: 3, -1
-4, 70i
Enter the x and y coordinates for line "H" separated by commas, for example: 3, -1
5, i
Enter the x and y coordinates for line "I" separated by commas, for example: 3, -1
2, -i
Enter the x and y coordinates for line "J" separated by commas, for example: 3, -1
1, 0
