input: Write a function in Python to print the Fibonacci series.
  
  ### Input:
  def printFibonacciSeries(n): 
    
      # Taking 1st two fibonacci nubers as 0 and 1 
      f1 = 0
      f2 = 1
      print(f1, f2, end = " ") 
    
      for i in range(2, n): 
          next_fib = f1 + f2 
          print(next_fib, end = " ") 
    
          # update values 
          f1 = f2 
          f2 = next_fib
    
  ### Output:
  assert printFibonacciSeries(5) == "0 1 1 2 3 "
  assert printFibonacciSeries(10) == "0 1 1 2 3 5 8 13 21 34 "
  assert printFibonacciSeries(0) == ""
  assert printFibonacciSeries(1) == "0 "
  assert printFibonacciSeries(2) == "0 1 "
output: def printFibonacciSeries(n): 
      if n > 0:
          f1 = 0
          f2 = 1
          print(f1, end=" ")
          if n > 1:
              print(f2, end=" ")
          for i in range(2, n): 
              next_fib = f1 + f2 
              print(next_fib, end=" ") 
              f1 = f2 
              f2 = next_fib
