Question

I’m writing a code for homework, it needs t o output the values for pascal’s triangle, but not in a triangle. for instance I input

pascalLine(2)

it outputs:

[1,2,1]

and for:

pascalLine(4)

it outputs:

[1,4,6,4,1]

I currently have this code and I believe it is far from complete, because It outputs a triangle.

def pascalLine(n):
  for rownum in range (n):
      newValue=1
      PrintingList = list()
      for iteration in range (rownum):
          newValue = newValue * ( rownum-iteration ) * 1 / ( iteration + 1 )
          PrintingList.append(int(newValue))
      print(PrintingList)
  print()

Answer 1

Assuming your original code to calculate row n is correct, you can just get rid of the outer loop:

def pascalLine(n):
    newValue=1
    row = [newValue]
    for i in range (n):
        newValue = (newValue * (n-i)) / ( i + 1 )
        row.append(newValue)

    print(row)
    print()
