How do get more control over loop increments in Python?

One option:

def drange(start, stop, step):
    while start < stop:
            yield start
            start += step

Usage:

for i in drange(0, 1, 0.01):
    print i

you can use list comprehensions either:

print([i for i in [float(j) / 100 for j in range(0, 100, 1)]])

if you want control over printing i then do something like so:

print(['something {} something'.format(i) for i in [float(j) / 100 for j in range(0, 100, 1)]])

or

list(i for i in [float(j) / 100 for j in range(0, 100, 1)])

for i in [float(j) / 100 for j in range(0, 100, 1)]:
    print i

Avoid compounding floating point errors with this approach. The number of steps is as expected, while the value is calculated for each step.

def drange2(start, stop, step):
    numelements = int((stop-start)/float(step))
    for i in range(numelements+1):
            yield start + i*step
Usage:

for i in drange2(0, 1, 0.01):
    print i
