All value in specific column must be in the same format, another thing we may want to convert entire column to specific format, and we can manipulate it by divided or convert to specific format, for example how to convert miles per gallon to l/100km we just divided by 235.215 as follow:
- To convert entire column:
df["column_name"] = 235/df["column_name"]
- To rename the title of column:
df.rename(columns={"coumns_name1":"column_name2"}, inplace=True)- To know the data type :
df["column_name"].tail(5) - Identify data type
df["column_name"].dtypes() - convert data type of column
df["column_name"] = df["column_name"].astype("int")
