[Python] Why do these objects bounce around the screen so fast and how do I slow them down?

I have these blocks that I have made that are in the Enemy_Block class. When I try to move them they like teleport around the screen. How to I slow these enemy blocks down. Please help, thanks.

I have tried putting that for-loop that spawns enemy blocks in and outside the loop. That's it.

pygame.draw.rect(screen,self.color,[self.x_cor,self.y_cor,self.length,self.width],0)
self.y_cor += self.move_y
self.x_cor += self.move_x
if self.x_cor == x_size - self.width:
self.x_cor = 0

# Fill the Screen Black
screen.fill(BLACK)
# Activate draw function in Block

#Spawn Enemy Blocks

The expected result is that the game will create ten enemy blocks that move around the screen kinda slow because my velocity is low. The result is that the blocks kinda teleport around the screen, because they are moving so fast.
