To convert a string column to an integer in a Pandas DataFrame, you can use the astype() method. To convert String to Int (Integer) from Pandas DataFrame
df['price'] = df['price'].astype('Int64') # convert data to int. return df 我收到一个错误:对象无法转换为IntegerDtype。 我试着解决这个问题,就像前面在一个SoF问题中提到的那样,首先转换为float,然后转换为int: def convert_price(df): df['price'] = df['price'].str.replace('$', '') ...

Hence, we will use the data frame round() method along with the astype() method for converting the float value to an integer value and getting the round-off result of these values.Let us assume that we have a value of 1.6 the round method will convert this value into 2 whereas the ...
