TypeError：类型为'int'的对象没有len（）？

Question

# Logistic Regression

# Importing the libraries
import numpy as np
import matplotlib.pyplot as plt
import pandas as pd

# Importing the dataset
dataset = pd.read_csv('Loan.csv')
X = dataset.iloc[:, 16: 17 ].values
y = dataset.iloc[:, 20].values


# Encoding categorical data
from sklearn.preprocessing import LabelEncoder, OneHotEncoder
labelencoder = LabelEncoder()
X[:, 0] = labelencoder.fit_transform(X[:, 0])
onehotencoder = OneHotEncoder(categorical_features = 1)
X = onehotencoder.fit_transform(X).toarray()

When i write code i get error at the end like object of type 'int' has no len()?

Answer 1

It was fixed after a correction was made:

onehotencoder = OneHotEncoder(categorical_features = [1]*)

I think it's because python wants us to specify which column, explaining the need for "[]".
