pd.read_csv读取txt文件后，按制表符分割，得出来列数为1，请问如何分割这一列呢？

train_original = pd.read_csv('H:/features_norm.txt', sep='\t', header=None, engine='python')

print(train_original.shape)

print(train_original.head(5))

文件内容分隔符是什么，下面制表符是可以拆分的

a= pd.read_csv(r'd:\test.txt', sep='\t', header=None, engine='python')
print(a.values)

输出

[['a' 'b' 'c']
 ['d' 'e' 'f']]
