pygame 运行心理学问卷

import pygame
import sys
from pygame.locals import *

# wait for keys to putdown
def waitForKeys(keysAllowed):
    key = False # initialize the key
    pygame.event.clear() # clear the event
    while not key:
        for i in pygame.event.get(): # for every event in the event list
            if i.type == pygame.KEYDOWN or i.type == pygame.KEYUP: # if the event type is keydown
                if i.key in keysAllowed : # if key is the special key
                # 如果是 if i.key ==  K_0 or K_1 or K_2 ,那么按任意一个键都将退出，因为 or 的逻辑成了（if i.key ==  K_0） or K_1 这种形式
                    print(i.key, pygame.key.name(i.key))
                    key = True # break the while loop 

    return 0 # reture the value

# draw a two sentences

    myFont = pygame.font.SysFont("华文宋体", 25,False, False) # create the font
    myStringSurface = myFont.render(myString, True,  (255,255,255), False) # create the string
    myString1 = "1 有点  2 中等 3 很多"

    mywin.blit(myStringSurface1, (1,100), None, 0) # draw another surface
    pygame.display.flip() # flip the window
    return 0 # return 0

myString = ["你好啊","我不好","吃了吗","枯井柘城","没有呢","那好吧"]

    displayOneQuestion(element)
    waitForKeys(keysAllowed)

# 注意点1 ： 如果 pygame.event.clear() # clear the event 这一句放在 while ：的开头，那么程序会非常慢，而且有的还会跳过，不知为什么。
# 注意点2：  如果是 if i.key ==  K_0 or K_1 or K_2 ,那么按任意一个键都将退出，因为 or 的逻辑成了（if i.key ==  K_0） or K_1 这种形式 ，而且if i.key == （K_0 or K_1）也是不行的。

这是一张问卷的问题的界面（当然问题是我瞎编的，并且也不是很美观，后期可以调整）

需要被试按键才能看下一题，按的键包括1,2,3,4,5

这是第二个问题的界面

这是完成5道题后的结果，我打印出了按键的ASC值，以及键的名称，可以看出名称为键盘上的数字按键。

总结：界面上的问题，问题的位置，答案的内容，答案的位置都可以设置，由于现在没有拿到问卷的内容，所以问卷内容是瞎写的。用pygame的主要优势是跳过了纸笔测验，而且可以将被试的反应（按键）存入数据库。

最近看到，做心理学问卷，用pyqt5,以及tkinter写GUI,要比我上面写的心理学问卷好的多。悲哀。

继续用的pygame , 但是对自己之前的工作，做了优化。

代码如下：

import pygame
import sys
from pygame.locals import *

# wait for keys to putdown
def waitForKeys(keysAllowed,theQuestion):
    key = False # initialize the key
    pygame.event.clear() # clear the event
    while not key:
        for i in pygame.event.get(): # for every event in the event list
            if i.type == pygame.KEYDOWN or i.type == pygame.KEYUP: # if the event type is keydown
                if i.key in keysAllowed : # if key is the special key
                # 如果是 if i.key ==  K_0 or K_1 or K_2 ,那么按任意一个键都将退出，因为 or 的逻辑成了（if i.key ==  K_0） or K_1 这种形式
                    result = "{0}_{1}_{2}_{3:，<30}{4}{5}".format(participantName,participantGender,participantAge,theQuestion,"按键是: ",pygame.key.name(i.key)) # format the string , the format not only can use print() function
                    print(result) # print the result
                    key = True # break the while loop 

    return result # reture the value

# draw a two sentences
def displayOneQuestion(myString):
    pygame.init() # initialize pygame
    mywin = pygame.display.set_mode((800,600), DOUBLEBUF|HWSURFACE) # create the window
    myFont = pygame.font.SysFont("华文宋体", 25,False, False) # create the font
    myStringSurface = myFont.render(myString, True,  (255,255,255), False) # create the string
    myString1 = "1 非常不符合  2 比较不符合 3 难以确定 4 比较符合 5 非常符合"
    myStringSurface1 = myFont.render(myString1, True, (255,255,255), None)

    surfaceHeight = myStringSurface.get_height() # get the suface width of picture one
    surfaceWidth = myStringSurface.get_width() # get the suface height of picture one
    surfaceHeight1 = myStringSurface1.get_height() # get the suface width of picture two
    surfaceWidth1 = myStringSurface1.get_width() # get the suface height of picture two
    finalSurfaceHeight = 250 - (surfaceHeight/2) # compute the half height of the picture one
    finalSurfaceWidth = 400 - (surfaceWidth/2) # compute the half width of the picture one
    finalSurfaceHeight1 = 250 - surfaceHeight1/2 # compute the half height of the picture two
    finalSurfaceWidth1 = 400 - surfaceWidth1/2 #compute the half width of the picture two

    mywin.blit(myStringSurface, (finalSurfaceWidth, 200), None, 0)
    # mywin.blit(myStringSurface, (400 - finalSurfaceWidth, 250 - finalSurfaceHeight), None, 0) # draw the font surface to another surface and put the font to the middle of the window
    mywin.blit(myStringSurface1, (finalSurfaceWidth1,310), None, 0) # draw another surface and put the font to the middle of the window
    pygame.display.flip() # flip the window
    return 0 # return 03

myString = ["第1题： 在社交场合，我总是显得不够自然（）",
                    "第2题： 我有话就说，从来憋不住（）",
                    "第3题： 在集体活动中，我总表现得很活跃（）",

participantNumber = input("请输入您的编号：") # collect participant number
participantName = input("请输入您的名字：") # collect participant name
participantGender = input("请输入您的性别：")  # collect participant gender
participantAge = input("请输入您的年龄：") # collect participant age
keysAllowed = [pygame.K_1, pygame.K_2, pygame.K_3, pygame.K_4, pygame.K_5] # set the allowed keys which participant can push
resultList = [] # create a empty list to collect element for writing file
for element in myString: # every element in the qestionaires
    displayOneQuestion(element) # display the image
    result = waitForKeys(keysAllowed, element) # the image will stay on the screen until participant push the keyboard
    resultList.append(result + '\n') # add the key which participant push to the empty list

# open a file
with open("C:/users/mike1/desktop/data/wechatCrawlData/personality/{0}_{1}.txt".format(participantNumber,participantName), "w", encoding = "utf-8") as f1:
    f1.writelines(resultList) # write the list to the file

# 注意点1 ： 如果 pygame.event.clear() # clear the event 这一句放在 while ：的开头，那么程序会非常慢，而且有的还会跳过，不知为什么。
# 注意点2：  如果是 if i.key ==  K_0 or K_1 or K_2 ,那么按任意一个键都将退出，因为 or 的逻辑成了（if i.key ==  K_0） or K_1 这种形式 ，而且if i.key == （K_0 or K_1）也是不行的。
# 注意点3 ：  format()函数不仅可以用于print()函数中，还可以用于文本的写入 with open()函数，比如本例中，object = format(), write(object)

上面的问卷题目只有三道题。
