Python: “If” function












1















This is probably really simple but I can't figure it out.



I have a bunch of lists and I want to call certain lists if they are in the range equal to a value x and any number between x-5 and x +5. i.e. x-5,x-4,x-3,x-2,x-1,x,x+1,x+2,x+3,x+4 and x+5.



At the moment I have



if sum(listname[i])==x:



if sum(listname[i])==x-1:



if sum(listname[i])==x-2:


etc



How can I do it so that it is combined in one "if" function.



I've been thinking on the lines of something like:



if sum(listname[i])==x-5>=x>=x+5:


or 



if sum(listname[i])==x or x-1 or x-2 ".. etc":


but neither work.



Can anybody shine some light on this?






python list if-statement range

  • This is pretty theoretical, can you make a Minimal, Complete, and Verifiable example with complete sample input and output? Also, your terminology is a bit shaky. if is not a function and you can't call lists. (We should be able to understand what you want with the MCVE, though.)

    Try this if x-5 <= sum(listname[i]) <= x+5:. If x is a real number x-5 cannot be superior to x+5

A scenario like if sum(listname[i])==x or x-1 or x-2 ".. etc": (which is not valid python) is usually solved with if value in range(start, stop, step):



So you would write:



if sum(listname[i) in range(x-2, x):

    # Code for this case here...

    It looks like you want to check if the sum of the list is between x - 5 and x + 5. To put it in one if statement is simply:



    s = sum(listname[i])
    
if s >= x - 5 and s <= x + 5:
    
  # do stuff

      From what I understand from your question. You what to check that whether sum(listname[i]) is between (x-5, x+5)



      You can do this in a single if assuming x is a possitive value:



      if (sum(listname[i]) >= (x - 5)) and (sum(listname[i]) <= (x+5))
