Why does the character disappear?

Question

Python

I tried to remove everything from the game that does not relate to the problem, here is the code that comes out

import pygame as pg

class player(object):
    def __init__(self, x, y, width, heigth):
        self.x = x
        self.y = y
        self.width = width

        self.jumpCount = 10
        self.standing = True

        self.walkLeft = []
        self.walkRight = []
        self.createSpriteList('Left')
        self.createSpriteList('Right')

    def draw(self, win):
        if self.walkCount + 1 >= 27:
            self.walkCount = 0

        if not self.standing:
            if self.left:
                win.blit(self.walkLeft[self. walkCount//3], (self.x, int(self.y)))
                self.walkCount += 1
        
            elif self.right:
                win.blit(self.walkRight[self.walkCount//3], (self.x, int(self.y)))
                self.walkCount += 1

        redraw() 
        

win.fill((255, 255, 255))
pg.display.update()

mainloop()

pg.quit()

When I press the spacebar the character just disappears, if I press the right or left, the character reappears

Answer 1

I figured it out. everything is ok
In the mainloop, here in this place:

if keys[pg.K_SPACE] and not man.isJump:
            man.isJump = True
            man.left = False
            man.right = False
            man.walkCount = 0

I removed

man.left = False
man.right = False
man.walkCount = 0

and everything started working
