Question about 'A Complete Tutorial to Learn Data Science with Python from Scratch'

When I enter the following code from the tutorial:
from sklearn.preprocessing import LabelEncoder
var_mod = [‘Gender’,‘Married’,‘Dependents’,‘Education’,‘Self_Employed’,‘Property_Area’,‘Loan_Status’]
le = LabelEncoder()
for i in var_mod:
df[i] = le.fit_transform(df[i])
df.dtypes

I get the error below. Can someone please advise? Thank you!

In [24]: for i in var_mod:
…: df[i] = le.fit_transform(df[i])
