如何有组织地写入文件?

text-files python

somebrick · 技术社区 · 8 年前

我有以下代码:

file = open('scores.txt','w')
playerscores = []
playernames = [['A'],['B'],['C'],['D'],['E'],['F']]   
for y in range(6):
    for z in range(5):
            print("Enter score from Judge",z+1,"for couple ",playernames[0+y],"in round 1:")
            playerscores.append(int(input()))    
MY_LIST = str(playerscores)
for_every = 4

playerscore[0:6]
playerscore[7:13]

等

1,1,1,1,1,1,1,1,1,1

[1,1,1,1,1,1]

我需要这样做

file = open('filename','r')

这里有一些代码可以满足您的需要,尽管它是从我的 get_data() 函数而不是来自 input() get_data() 呼叫一旦完成程序开发。

关键思想是,除了将输入数据的整数版本保存到 playerscores 我们还将其以原始字符串形式保存在一个名为 row

from random import seed, randrange

# Seed the randomizer
seed(42)

# Make some fake data, to simulate user input.
# Print & return a random number from 1 to 5, in string form
def get_data():
    n = str(randrange(1, 6))
    print(n)
    return n

playernames = ['A', 'B', 'C', 'D', 'E', 'F']

numjudges = 5

playerscores = []
scoresfile = open('scores.txt', 'w')

for players in playernames:
    row = []
    for z in range(1, numjudges + 1):
        print("Enter score from Judge", z, "for couple ", players, "in round 1:")
        data = get_data()
        playerscores.append(int(data))
        row.append(data)
    scoresfile.write(','.join(row) + '\n')
    print()
scoresfile.close()
