在Python中使用Numpy / Pandas读取文本文件

Question

I have an unlabeled dataset which contains 101 columns ie no column have any heading, now I want to start reading from column 2 to end ie 101th column. I am trying with this code :

data = np.loadtxt('structure-safety.inp', usecols = [2, 101])
or 
data = pd.read_fwf('structure-safety.inp', usecols = [2,1,101])

I also tried with usecols = [2, :], [2:101] or used () instead of [] but in vain, can anyone help me here with this problem.

Answer 1

Try:

data = pd.read_fwf('structure-safety.inp', usecols=list(range(2,102))

Keep in mind that the columns are numbered from 0. So column 2 is actually the third column.

Or you can drop a column:

data = pd.read_fwf('structure-safety.inp')
data = data.drop(df.columns[0:2], axis=1)
