Python | Pandas TimedeltaIndex.get_level_values

Last Updated : 28 Dec, 2018

Python is a great language for doing data analysis, primarily because of the fantastic ecosystem of data-centric python packages. Pandas is one of those packages and makes importing and analyzing data much easier.

Pandas TimedeltaIndex.get_level_values() function return an Index of values for requested level, equal to the length of the index.

Syntax : TimedeltaIndex.get_level_values(level)
Parameters :
level : level is either the integer position of the level in the MultiIndex, or the name of the level.
Return : self, as there is only one level in the Index.

Example #1: Use TimedeltaIndex.get_level_values() function to find all the values present in the 0th level of the given TimedeltaIndex object.

# importing pandas as pd
import pandas as pd
  
# Create the TimedeltaIndex object
tidx = pd.TimedeltaIndex(data =['3 days 06:05:01.000030', '1 days 06:05:01.000030', 
                                '3 days 06:05:01.000030', '1 days 02:00:00', 
                                                 '21 days 06:15:01.000030'])
  
# Print the TimedeltaIndex object
print(tidx)

Output :

Now we will use the TimedeltaIndex.get_level_values() function to find all the values in 0th level

# print values in 0th level
tidx.get_level_values(0)

Output :

As we can see in the output, the TimedeltaIndex.get_level_values() function has returned all the values present in the 0th level of tidx object. This object has only one level.

Example #2: Use MultiIndex.get_level_values() function to find all the values present in the 1st level of the given MultiIndex object.

# importing pandas as pd
import pandas as pd
  
# Create the MultiIndex object
midx = pd.MultiIndex.from_arrays((['AB', 'BC', 'CD', 'DE'], 
                                  ['EF', 'FG', 'GH', 'HI']))
  
# Print the MultiIndex object
print(midx)

Output :

Now we will use the MultiIndex.get_level_values() function to find all values in the 1st level

# print values in 1st level
midx.get_level_values(1)

Output :

As we can see in the output, the MultiIndex.get_level_values() function has returned all the values present in the 1st level of midx object.
