To find unique values in multiple columns, we will use the pandas.unique() method. This method traverses over DataFrame columns and returns those values whose occurrence is not more than 1 or we can say that whose occurrence is 1.Syntax:pandas.unique(values) # or df['col'].unique() ...
Write a R program to create a data frame using two given vectors and display the duplicated elements and unique rows of the said data frame. Sample Solution: R Programming Code : # Create vector 'a' with specified valuesa=c(10,20,10,10,40,50,20,30)# Create vector 'b' with specified...
To look for missing values, use the built-in isna() function in pandas DataFrames. By default, this function flags each occurrence of a NaN value in a row in the DataFrame. Earlier you saw at least two columns that have many NaN values, so you should start here with your clea...
