import pandas as pd import numpy as np levels = ['foo', 'bar', 'baz', 'qux'] codes = np.random.randint(0, 4, size=100) cats = pd.Categorical.from_codes(codes, levels, name='myfactor', ordered=True) data = pd.DataFrame(np.random.randn(100 Index performance between any two dates can be calculated by dividing the ending index value by the beginning index value as follows. Using our hypothetical index as an example: Day 1 index value = 100.0. Day 4 index value = 103.1 ((103.1 / 100) -1) x 100 = 3.1%. Why do index values vary so widely across indexes and index providers? 2021-01-19 · Level of 1 is 3 Level of 2 is 2 Level of 3 is 1 Level of 4 is 3 Level of 5 is 2 Time Complexity of getLevel() is O(n) where n is the number of nodes in the given Binary Tree.

BMI values between 16 and 40 were plotted against the reference (BMI The difference between level of significance (alpha) and the p-value. A low p-value says it is unlikely that we would get the observed 4.1.1 SAIDI (System Average Interruption Duration Index) . Since this information is not possible to obtain in this case, the peak load is estimated based on As in [5], the national level values of the normalized interruption costs are "5f999cc7-50e8-4eeb-87c4-b49aa55f010c"],"description":""},"upholstery":{"index":0 level and the total car tax with your Toyota dealer","co2Value":"CO2 {value}" ":"Get part exchange value","tradeinEnterLicensePlate":"Enter license plate" GRI Index.

Calling object, as pandas.Index.get_level_values¶ Index.get_level_values (level) [source] ¶ Return an Index of values for requested level, equal to the length of the index. The.tolist () method of a MultiIndex gives a list of tuples for all the levels in the MultiIndex. For example, with your example DataFrame, df.index.tolist () # => [ (1, 4, 10), (1, 4, 11), (1, 5, 12), (2, 5, 13), (2, 6, 14), (3, 7, 15)] So here are two ideas: An alternative approach is to find the number of levels by calling df.index.levels[level_index] where level_index can be inferred from df.index.names.index(level_name). In the above example level_name = ‘co’. The proposed answer by @Happy001 computes the unique which may be computationally intensive. pandas.Index.get_level_values It will return an Index of values for the requested level. This is primarily useful to get an individual level of values from a MultiIndex, but is provided on Index as well for compatibility.

There's an important detail to notice here.
