Python Split（）IndexError

2024-04-28 • 问答

代码下降给了我想要的结果，但是它却不断给我同样的错误，并且程序没有完成。

totalIdadesM = 0
totalIdadesH = 0

countM = 0
countH = 0

with open("info.txt","r") as infoFile:
    for line in infoFile:
        if line[1] == "M":
            for line in infoFile:
                dados = line.split("=")
                print(dados)
                idade,peso = dados[1].split(",")

                print(idade)
                print(peso)


                if idade.isdigit():
                    totalIdadesM += int(idade)
                    countM += 1

        print(countM)
def calcMedia(total,num):
    media = total / num
    return media

那是错误

['Ana'，'24，55 \ n']

24 55

['Ines'，'30，60 \ n']

30 60

['Sofia'，'18，49 \ n']

18 49

['Carla'，'44，64 \ n']

44 64

['\ n']

回溯（最近一次通话最后一次）：文件“ ex4.1.py”，第13行，在          idade，peso = dados [1] .split（“，”）IndexError：列表索引超出范围

输入如下：

[Mulheres] Ana = 24,55 Ines = 30,60 Sofia = 18,49 Carla = 44,64

[Homens] Joao = 20,75 Tiago = 55,80 Quim = 59,69

您的代码空了一行。您可以这样跳过所有空行：

for line in infoFile:
    line = line.strip()
    if not line: # empty line
        continue # skip the body and go staring to next iteration

    dados = line.split("=")
    ...

我不确定的一件事就是为什么要遍历infoFile 两次。当您进行迭代时，您正在从中读取内容，例如，在这里，第一行将被跳过：

for line in infoFile:
    # read first line
    if line[1] == "M":
        for line in infoFile:
            # first line has already been read,so read the second line,# thus skipping the first one altogether
            ...
        # the loop will be exited when there'll be no more data to read
    # so the outer loop will terminate since there's nothing to iterate over anymore
