So, I have this script that puts in a list every minute in 24 hours
hour=[]
i=0 t=-(1.0/60.0)
while i<24*60:

hour.append([t])
In many cases you can write
for i in range(...):
...
instead of incrementing manually.
When it is doing the cicle it can have all the decimal numbers, but I
need to print the result with only 4 decimal numbers
How can I define the number of decimal numbers I want to print in this
case? For example with 4 decimal numbers, it would print:
0.0000 0.0167 0.0333 ...
Can you help?
for i in range(24*60):
... print "{:.4f}".format(i/60.0)
...
0.0000 0.0167 0.0333 0.0500 [...]
23.9500 23.9667 23.9833

and a list comprehension would streamline things further
t=[round(x*1.0/60),4 for x in range(1440)] #compatible with V2.7 & V3.0)
Really?
