CSV的思想是在每一行存储相同的数据格式。这样地:

gameId,user1Id,user1Name,user1Pass,user1Score,user2Id,user2Name,user2Pass,user2Score

下面是代码:

import csv
import random
from passlib.apps import custom_app_context as pwd_context

game_id = random.randint(1000, 999999)
data = [game_id]
for i in range(2):
    data.append(random.randint(1000, 9999))
    data.append(input('Enter player {} name: '.format(i+1)))
    p_pass = input('Enter/Create player {} password: '.format(i+1))
    data.append(pwd_context.hash(p_pass))
    data.append(0)

print('Your game unique ID is: ', game_id)

with open('database.csv', 'a', newline='') as f:
    writer = csv.writer(f)
    writer.writerow(data)

输出 database.csv :

489042,6139,User1,$6$rounds=656000$YzvCUZobix403Zjm$ApMp4Zo7NzMFcvW3KRYwlcPl9OWHdGONCOQztZwdeUP/fc/6cZFPpIsREGVwvyGk30IqgYrJHq0I5NqBr1KIc.,0,8622,User2,$6$rounds=656000$x50kIsTvVHSBYqfM$/.TCk2qkNxbDRN5r1vyI5gPZ6YWJx5nL1gpUHdkc64trbAqbJHNDfHTJaEaieEE8Pt9IC45Vm4ueytYaMZ13u1,0

回复了 Alderven 创建的主题 » 将包含字符串和整数的列表中的元素求和,并将答案放入另一个列表python中

您可以使用单循环:

lst = ['student1', 10, 20, 40, 'student2', 20, 20, 40, 'student3', 20, 30, 40, 'student4', 20, 10, 30]
result = []
for i in range(0, len(lst), 4):
    result.extend((lst[i], sum(lst[i+1:i+4])))

输出:

['student1', 70, 'student2', 80, 'student3', 90, 'student4', 60]

如果每个学生的分数不同,例如:

lst = ['student1', 10, 20, 'student2', 10, 20, 30, 'student3', 10, 20, 30, 40, 'student4', 10, 20, 30, 40, 50]

然后:

s = 0
result = [lst[0]]
for i in lst[1:]:
    try:
        s += int(i)
    except ValueError:
        result.extend((s, i))
        s = 0
result.append(s)

输出:

['student1', 30, 'student2', 60, 'student3', 100, 'student4', 150]

这个只适用于 second image :

from PIL import Image, ImageFilter
import pytesseract

img = Image.open('TcjXJ.jpg')
img2 = img.filter(ImageFilter.BLUR)
pixels = img2.load()
width, height = img2.size
x_ = []
y_ = []
for x in range(width):
    for y in range(height):
        if pixels[x, y] == (255, 255, 255):
            x_.append(x)
            y_.append(y)

img = img.crop((min(x_), min(y_),  max(x_), max(y_)))
text = pytesseract.image_to_string(img, lang='eng', config='-c tessedit_char_whitelist=ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789')
print(text)

你有输出:

TN 99 F 2378
