Question

Basically I want to go from -1 to 1 in n steps, including -1 and 1:

x = -1.0
n = 21

for i in range(n):
    print x
    x += 0.01

-1.0 -0.9 -0.8 ... 0.8 0.9 1.0

How can I write this in the most elegant, simplest way for any n value?

Answer 1

startValue = -1.0
intervalLength = 2.0
numberOfSteps = 14
increasePerStep = intervalLength / numberOfSteps

print startValue

x = startValue
for i in range (numberOfSteps):
    x += increasePerStep
    print x
