Question

import csv

with open('Football_data.csv') as csvfile:
readCSV = csv.reader(csvfile, delimiter=',')

dates = []
homeTeam = []
awayTeam = []
fullTimeHomeGoals = []
fullTimeAwayGoals = []
fullTimeResult = []


for row in readCSV:
    #ignore row[0]
    date = row[1]
    home = row[2]
    away = row[3]
    FTHG = row[4]
    FTAG = row[5]
    FTR = row[6]

    dates.append(date)
    homeTeam.append(home)
    awayTeam.append(away)
    fullTimeHomeGoals.append(FTHG)
    fullTimeAwayGoals.append(FTAG)
    fullTimeResult.append(FTR)



    print(date, home,FTHG, FTAG, away)

我正在尝试将CSV文件中的数据转换为整数。

我尝试过

FTHG = int(row[4])
FTAG = int(row[5])

但是出现以下错误：

Traceback (most recent call last):
File "C:/Users/*****/PycharmProjects/untitled/first.py", line 19, in 
<module>
FTHG = int(row[4])
ValueError: invalid literal for int() with base 10: 'FTHG'

为了对CSV文件中的足球数据进行一些分析，代表得分目标的值需要存储为整数。由于CSV文件中的所有数据都是字符串数据，因此我需要转换。我使用的语法确实可以在循环之外使用。

Answer 1

尝试：

import csv

with open('Football_data.csv') as csvfile:
    readCSV = csv.reader(csvfile, delimiter=',')

    ################ This is the header of each columns
    next(readCSV) ## This line reads it so it is not read
    ################ when iterating in the for loop

# ... #

将字符串列表转换为整数PYTHON
