在python列表中将字符串递增n次

Question

I have a list like below in python.

a = ['191.10', '10.0']

Now I want to create another list like below

b = ['191.10', '10.0', '10.1', '10.2', '10.3' and so on till '10.255']

Basically Increment the second string with 0.1

How can I achieve that.

Answer 1

Here's one way using a list comprehension:

a = ['191.10', '10.0']

b = a + ['10.'+str(i) for i in range(1, 256)]

Result:

['191.10', '10.0', '10.1', '10.2', ..., '10.254', '10.255']

Answer 2

The most obvious way to accomplish this is probably with the append() statement. Also I'm assuming you meant to write "b = ['191.10, '10.0', '10.001', '10.002', '10.003' and so on till '10.255']" here.

 a = ['191.10', '10.0']

 for n in range(1, 255):
      a.append(10 + (0.001*n))
