How do I check horizontal and vertical collision in pygame?

Question

So, I want to make a stickman parkour game in pygame. But I don't know how to check collision in horizontal and vertical. I try search online or watch youtube videos but I could'nt under stand what they do.

I want the check collision function to be like:

if collide(objectA,objectB,"Up"):
  stick.dy = 0
if collide(objectA,objectB,"Down"):
  stick.dy = 0
if collide(objectA,objectB,"Right"):
  stick.dx = 0
if collide(objectA,objectB,"Left"):
  stick.dx = 0

Here is my code:

import pygame
from spr import*
import sys
pygame.init()

win = pygame.display.set_mode((700,500))
pygame.display.set_caption("Stickman Parkour")

stick = Stick(30,30)
blocks = []
jump = False
land = False
frc = .91
grv = .2

run = True
while run:
    pygame.time.delay(15)
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False
    stick.dx *= frc
    stick.dy += grv
    stick.x += stick.dx
    stick.y += stick.dy
    
    blocks.append(Brick(0,100,False,0,0,0,30,30))
    keys = pygame.key.get_pressed()
    if keys[pygame.K_d]:
        stick.dx = 3
        stick.x += 3
    if keys[pygame.K_a]:
        stick.dx = -3
        stick.x -= 3
    if keys[pygame.K_w]:
        stick.dy = -3
        jump = False
        stick.y -= 3
    if keys[pygame.K_s]:
        stick.y +=3
    
    if keys[pygame.K_a] and keys[pygame.K_d]:
        frc = 0
    else:
        frc = .91
    
    win.fill((200,200,200))
    for block in blocks:
        pygame.draw.rect(win,(0,0,0),(block.x,block.y,block.w,block.h))
        if collide(stick,block):
            jump = True
            land = True

            if not keys[pygame.K_w]:
                stick.dy = 0
                stick.y = block.y - stick.h
        else:
            jump = False
    pygame.draw.rect(win,(225,0,0),(stick.x,stick.y,30,30))
    pygame.display.flip()

sys.exit(0)

Can someone help me?
