Can a column in dataframe contains different datatypes items?
Column inside any data frame can only have one data type for all the cells of those columns. You can see it using:
df.describe() or df.info()
If i change one value of a column in csv file then whole column values are changed for example i have a column type int64 and i change one item from any integer to string then whole items types are changed to string by default when we read file like df = pandas.read_csv(filename). Actually i have to find item/items in a df column who have different datatypes from others like if i have column type int64 and there is one value of datatype object or float64 types in that column then i have to fetch that value as well as the row number of that value.
