我在一个很长的项目上工作，我从保存在我的校园网络系统中的文件中读取，当读取文件时，如果我删除列表底部的空白区域，但是当我离开它们时（如教授希望）我得到一个错误，“int（无效的文字）与基数10：'日期'”我尝试了几个不同的选项来忽略空格但没有一个工作 - 我尝试过的列表
with open("C:\\Users\\Brayd\OneDrive\\Documents\\2015HomicideLog_FINAL.txt") as f_in:
lines = (line.rstrip() for line in f_in)
lines = list(line for line in lines if line)
for line in file: if not line.strip(): print("it is empty line")
with open("fname.txt") as file:
for line in file:
if not line.strip():
file.close()
with open file as f_in: lines = list(line for line in (l.strip() for l in f_in) if line)
没有什么工作，这是我在删除文件中的空白时使用的，它完美地工作
file = open("C:\\Users\\Brayd\OneDrive\\Documents\\2015HomicideLog_FINAL.txt" , "r")
lines=file.readlines()[1:]
file.close()
我一直在努力让它在空白区域工作12个小时，现在没有任何运气......任何想法的人？
这是文本文件的样子 -

根据我从评论中收集的内容，您可能有几个选项，我会做的是：
with open("file.txt") as f:
data = f.readlines()
headersRaw = data[0].split()
headersFinal = [headersRaw[0], # Date
headersRaw[1]+" "+headersRaw[2], # Event #
headersRaw[3], # Time
headersRaw[4]+" "+headersRaw[5], # Victim name
headersRaw[6], # V
headersRaw[7], # R/G
headersRaw[8]+" "+headersRaw[9] # V Age
]
i = 1
computedData = []
while data[i].split()[O].isdigit():
rawData = data[i].split()
computedData.append([rawData[0], # Date
rawData[1], # Event #
rawData[2], # Time
rawData[3]+" "+rawData[4], # Victim name
rawData[5], # V
rawData[6], # R/G
rawData[7] # V Age
])
i += 1
所以我们只是检查下一行是否以数字开头
with open("file.txt") as f:
data = f.readlines()
headersRaw = data[0].split()
headersFinal = [headersRaw[0], # Date
headersRaw[1]+" "+headersRaw[2], # Event #
headersRaw[3], # Time
headersRaw[4]+" "+headersRaw[5], # Victim name
headersRaw[6], # V
headersRaw[7], # R/G
headersRaw[8]+" "+headersRaw[9] # V Age
]
i = 1
computedData = []
while len(data[i].split()[O]) == 6:
rawData = data[i].split()
computedData.append([rawData[0], # Date
rawData[1], # Event #
rawData[2], # Time
rawData[3]+" "+rawData[4], # Victim name
rawData[5], # V
rawData[6], # R/G
rawData[7] # V Age
])
i += 1
因此，我们将检查表中的下一个数据是否包含长度为6的日期值
您的数据可能是不同的，甚至是错误，也可能是6位数或整数，因此请确保您在while循环上执行的检查适合于表后面的数据。
它可能不是最好的解决方案，但没有更多的信息，事后可能会发生什么，有点难以提出完美的检查。如果可以的话，我建议添加一些破折号或者你可以轻松检查txt文件的东西。
