Python | Pandas TimedeltaIndex.is_monotonic_increasing

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.is_monotonic_increasing attribute return True if the index value are monotonically increasing. It return True even when the values are equal.

Syntax: TimedeltaIndex.is_monotonic_increasing

Return : boolean

Example #1: Use TimedeltaIndex.is_monotonic_increasing attribute to check if the TimedeltaIndex object is monotonic increasing or not.

# importing pandas as pd
import pandas as pd

# Create the TimedeltaIndex object
tidx = pd.TimedeltaIndex(start ='1 days 02:00:00', periods = 5, freq ='T')

# Print the TimedeltaIndex
print(tidx)

Output :

Now we will check if the TimedeltaIndex object is monotonic increasing or not.

# check if tidx is monotonic increasing or not
tidx.is_monotonic_increasing

Output :

As we can see in the output, the TimedeltaIndex.is_monotonic_increasing attribute has returned True indicating that value in tidx object is monotonically increasing.

Example #2: Use TimedeltaIndex.is_monotonic_increasing attribute to check if the TimedeltaIndex object is monotonic increasing or not.

# importing pandas as pd
import pandas as pd

# Create the TimedeltaIndex object
tidx = pd.TimedeltaIndex(data =['-1 days 2 min 3us', '1 days 06:05:01.000030',
                                                '-1 days + 23:59:59.999999'])

# Print the TimedeltaIndex
print(tidx)

Output :

Now we will check if the TimedeltaIndex object is monotonic increasing or not.

# check if tidx is monotonic increasing or not
tidx.is_monotonic_increasing

Output :

As we can see in the output, the TimedeltaIndex.is_monotonic_increasing attribute has returned False indicating that value in tidx object is not monotonically increasing.
