Python Split（）索引器

下降的代码给了我想要的结果，但它一直给我相同的错误，程序无法完成

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

这就是错误所在

['Ana'，'24,55\n']

2455

['Ines'，'30,60\n']

3060

['Sofia'，'18,49\n']

18 49

['Carla'，'44,64\n']

44 64

['\n']

回溯（最近一次调用last）：文件“ex4.1.py”，第13行，在 idade，peso=dados[1]。拆分（“，”）索引器：列表索引超出范围

输入如下：

[Mulheres]安娜=24,55伊内斯=30,60索非亚=18,49卡拉=44,64

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

你的代码出现空行。您可以使用以下命令跳过所有空行：

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("=")
    ...

有一件事我不确定，那就是为什么要在

infoFile

上迭代两次。当您进行迭代时，您正在从中读取，例如，这里将跳过第一行：

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

它会在错误之前打印出

['\n']

，所以这可能是

护墙板

，显然在这种情况下

护墙板[1]

是一个错误。这意味着

行

是

'\n'

。
