Alternatively, to convert multiple string columns to integers in a Pandas DataFrame, you can use theastype()method. # Multiple columns integer conversiondf[['Fee','Discount']]=df[['Fee','Discount']].astype(int)print(df.dtypes)# Output:# Courses object# Fee int32# Duration object# Discount...
As you can see, the first column x1 has the object dtype (note that pandas stores strings as objects). This shows that we have converted the boolean data type of our input data set to a character string object. Example 2: Replace Boolean by String in Column of pandas DataFrame ...
