python 常用函数用法

pygame

初始化

pygame.init()

创建窗口

_screen_ = pygame.display.set_mode((_x_, _y_))
pygame.display.set_caption(_name(string)_)

显示图片

_screen_.blit(_image_, (_x_, _y_))

加载图片

_name_ = pygame.image.load(_image_)

修改图片

_name_ = pygame.transform.rotozoom(_origine_name_, _rad_, _k_of_size_)

获取图片长宽

_x_, _y_ = _image_.get_size()

加载汉字

FONT= pygame.font.Font(pygame.font.match_font('Comic Sans MS'), _size_)

打印文字

screen.blit(font.render(_string_, False, '_color_'), (_x_, _y_))

常用按键检测

# events
for event in pygame.event.get():
    # quit
    if event.type == pygame.QUIT:
        sys.exit()
    if event.type == pygame.KEYDOWN:

        if event.key == 119:

            history_W = True

        if event.key == 115:
            hero.derta_y += 1

            hero.nxt_time = hero.sped_up_time + 9
        # PAUSE P 112

math

开根 sqrt()

dr = math.sqrt(x)

开数组

_a_ = []

time

获取当前时间

_time_ = time.time()

none

在数组中加入元素

_a_.append(_element_)

文件输入输出

with open('_txt_', 'r')as TT:
    lst_record = float(TT.read())
with open('_txt_', 'w')as TT:
    TT.write(str(t))
