使用 python 读取 txt 文件中的列时出错

Question

I have a txt file with 1150 lines and 5 columns. The columns are separated with a tab. I want to get arrays containing a certain column of the txt file. I use the following code to get the columns:

f = open(file, "r")
lines=f.readlines()
result=[]
for x in lines:
    result.append(x.split('\t')[0])
f.close()

With this I get all the values of my first column, but when I want to get the second column with

result.append(x.split('\t')[1])

I get an IndexError: list index out of range

How can I solve this problem?

Answer 1

Try printing the lenght of each x within the loop:

print(len(line.split('\t')))
