fps = 90
fpsclock = pygame.time.Clock()  
while True:
    for event in pygame.event.get():
        if event.type == QUIT:
            sys.exit()
            a = False
        keys = pygame.key.get_pressed()
        if keys[pygame.K_SPACE]:
            #pygame.key.set_repeat(10,50)
            is_jump = True
            if True and icony <=340:
                icony -= jump_count**2*0.4*direction
                jump_count -= 1
                if jump_count == 0 :
                    direction = direction*-1
                if jump_count == -10:
                    is_jump = False 
                    jump_count = 10
                    direction = 1
                    icony = 340
            pygame.time.delay(10)
    fpsclock.tick(fps)
    pygame.display.update()

我希望它跳起来，然后停一秒钟左右，然后再跳，而不是连续跳。请帮忙

这是Indentation 的问题。执行跳转的代码必须在应用循环而不是事件循环中执行。
除此之外，您的代码中还有一些逻辑问题。见How can I do a double jump in pygame?或python, pygame - jumping too fast?

fps = 90
fpsclock = pygame.time.Clock()  
run = True
while run:
    for event in pygame.event.get():
        if event.type == QUIT:
            run = False
    
    #INDENTATION
    #<--|
    keys = pygame.key.get_pressed()
    if not is_jump and keys[pygame.K_SPACE]:
        is_jump = True
    if is_jump:
        icony -= jump_count**2*0.4*direction
        jump_count -= 1
        if jump_count == 0:
            direction = direction*-1
        if jump_count == -10:
            is_jump = False 
            jump_count = 10
            direction = 1
            icony = 340

    # [...]

    pygame.display.update()
    fpsclock.tick(fps)

小例子：

import pygame, sys
from pygame.locals import * 

pygame.init()
screen = pygame.display.set_mode((500, 500))

is_jump = False 
jump_count = 10
direction = 1
icony = 340

fps = 90
fpsclock = pygame.time.Clock()  
run = True
while run:
    for event in pygame.event.get():
        if event.type == QUIT:
            run = False
    
    keys = pygame.key.get_pressed()
    if not is_jump and keys[pygame.K_SPACE]:
        is_jump = True
    if is_jump:
        icony -= jump_count**2*0.4*direction
        jump_count -= 1
        if jump_count == 0:
            direction = direction*-1
        if jump_count == -10:
            is_jump = False 
            jump_count = 10
            direction = 1
            icony = 340

    screen.fill(0)
    pygame.draw.circle(screen, (255, 0, 0), (250, icony), 10)
    pygame.display.update()
    fpsclock.tick(fps)

pygame.quit()
sys.exit()
