To return number of unique elements in the Index object, use the index.nunique() method in Pandas. At first, import the required libraries −import pandas as pdCreating Pandas index −index = pd.Index([50, 10, 70, 110, 90, 50, 110, 90, 30]) Display the Pandas index −print("Pandas Index...", index)Get the number of unique values in the index −print("Count of unique values...", index.nunique()) ExampleFollowing is the code −import pandas as pd # Creating Pandas index index = pd.Index([50, 10, 70, 110, 90, 50, 110, 90, 30]) # Display the Pandas index print("Pandas Index...", index) # Return the number of elements in ...

To return unique values in the index, use the index.unique() method in Pandas. At first, import the required libraries -import pandas as pdCreating Pandas index −index = pd.Index([10, 50, 70, 10, 90, 50, 10, 30]) Display the Pandas index −print("Pandas Index...", index)Get the unique values from the index. Unique values are returned in order of appearance, this does NOT sort −index.unique() ExampleFollowing is the code −import pandas as pd # Creating Pandas index index = pd.Index([10, 50, 70, 10, 90, 50, 10, 30]) # Display the Pandas index print("Pandas Index...", index) # Return the number of elements ...

To mask and replace NaNs with a specific value, use the index.putmask() method. Within that, set the index.isna() method.At first, import the required libraries -import pandas as pd import numpy as npCreating Pandas index with some NaNs −index = pd.Index([5, 65, 10, np.nan, 75, np.nan]) Display the Pandas index −print("Pandas Index...", index)Mask and replace NaN index values with a specific value −print("Mask...", index.putmask(index.isna(), 111)) ExampleFollowing is the code −import pandas as pd import numpy as np # Creating Pandas index with some NaNs index = pd.Index([5, 65, 10, np.nan, 75, np.nan]) # Display the Pandas index print("Pandas Index...", ...

To return a new Index of the values set with the mask, use the index.putmask() method in Pandas. At first, import the required libraries −import pandas as pdCreating Pandas index −index = pd.Index([5, 65, 10, 17, 75, 40]) Display the Pandas index −print("Pandas Index...", index)Mask and place index values less than 3 with a value 111 −print("Mask...", index.putmask(index < 30, 111)) ExampleFollowing is the code −import pandas as pd # Creating Pandas index index = pd.Index([5, 65, 10, 17, 75, 40]) # Display the Pandas index print("Pandas Index...", index) # Return the number of elements in the ...

To return a new Timedelta ceiled to this resolution, use the timedelta.ceil() method. With that, set the resolution using the freq parameter.At first, import the required libraries −import pandas as pdTimeDeltas is Python’s standard datetime library uses a different representation timedelta’s. Create a Timedelta objecttimedelta = pd.Timedelta('6 days 1 min 30 s') Display the Timedeltaprint("Timedelta...", timedelta)Return the ceiled Timestamp ceiled to days frequencyres = timedelta.ceil(freq='D') ExampleFollowing is the code import pandas as pd # TimeDeltas is Python’s standard datetime library uses a different representation timedelta’s # create a Timedelta object timedelta = pd.Timedelta('6 days 1 min 30 s') # ...

To return a new Index of the values selected by the indices, use the index.take() method in Pandas. At first, import the required libraries -import pandas as pdCreating Pandas index −index = pd.Index(['Electronics', 'Accessories', 'Decor', 'Books', 'Toys'], name ='Products') Display the Pandas index −print("Pandas Index...", index)Getting a new index of the values selected by indices −print("A new Index of the values selected by the indices...", index.take([1, 2]))ExampleFollowing is the code −import pandas as pd # Creating Pandas index index = pd.Index(['Electronics', 'Accessories', 'Decor', 'Books', 'Toys'], name ='Products') # Display the Pandas index print("Pandas Index...", index) # Return ...

To return the seconds from Timedelta object, use the timedelta.seconds property. At first, import the required libraries −import pandas as pdTimeDeltas is Python’s standard datetime library uses a different representation timedelta’s. Set string input for seconds using unit 's'. Create a Timedelta objecttimedelta = pd.Timedelta('1 min 30 s') Display the Timedeltaprint("Timedelta...", timedelta)Return the seconds valuetimedelta.seconds ExampleFollowing is the code import pandas as pd # TimeDeltas is Python’s standard datetime library uses a different representation timedelta’s # set string input for seconds using unit 's' # create a Timedelta object timedelta = pd.Timedelta('1 min 30 s') # display the ...

To return the seconds from Timedelta object, use the timedelta.seconds property. At first, import the required libraries −import pandas as pdTimeDeltas is Python’s standard datetime library uses a different representation timedelta’s. Set integer input for seconds using unit 's'.

To replace index values where the condition is False, use the index.isin() method in Pandas. At first, import the required libraries −import pandas as pdCreating Pandas index −index = pd.Index(['Electronics', 'Accessories', 'Decor', 'Books', 'Toys'], name ='Products') Display the Pandas index −print("Pandas Index...", index)Replace values where condition is False. Here, except the 'Decor', every other element gets replaced −print("Replace index vales where condition is False...", index.where(index.isin(['Decor']), 'Miscellaneous'))ExampleFollowing is the code −import pandas as pd # Creating Pandas index index = pd.Index(['Electronics', 'Accessories', 'Decor', 'Books', 'Toys'], name ='Products') # Display the Pandas index print("Pandas Index...", index) # Return the ...
