I keep getting this error for my simple python program TypeError float object cannot be interpreted as an integer

Question

I don t understand why I can t use my variable c   code   from turtle import    speed 0  hideturtle   c   450  def grid x y a       seth 0      pu       goto x y      pd       for i in range 4           forward a          rt 90      for i in range c 10           seth 0          forward 10          rt 90          forward c          backward c      for i in range c 10           seth 0          rt 90          forward 10          rt 90          forward c          backward c      pu       goto a 10 0      write  x       goto 0 a 10      write  y       pd    grid 0 0 c  grid -c 0 c  grid -c c c  grid 0 c c    I get the following error message   Traceback  most recent call last     File  C  Users nick Desktop gridv2 py   line 35  in  lt module gt      grid 0 0 c    File  C  Users nick Desktop gridv2 py   line 15  in grid     for i in range c 10   TypeError   float  object cannot be interpreted as an integer

range   can only work with integers  but dividing with the   operator always results in a float value    gt  gt  gt  450   10 45 0  gt  gt  gt  range 450   10  Traceback  most recent call last     File   lt stdin gt    line 1  in  lt module gt  TypeError   float  object cannot be interpreted as an integer   Make the value an integer again   for i in range int c   10      or use the    floor division operator   for i in range c    10

As shown below  range only supports integers    gt  gt  gt  range 15 0  Traceback  most recent call last     File   lt stdin gt    line 1  in  lt module gt  TypeError  range   integer end argument expected  got float   gt  gt  gt  range 15   0  1  2  3  4  5  6  7  8  9  10  11  12  13  14   gt  gt  gt    However  c 10 is a float because   always returns a float     Before you put it in range  you need to make c 10 an integer   This can be done by putting it in int   range int c 10     or by using     which returns an integer   range c  10

Also possible is to fix this with np arange   instead of range which works for float numbers  import numpy as np for i in np arange c 10

User · Answer

In   for i in range c 10     You re creating a float as a result - to fix this use the int division operator   for i in range c    10
