Python Pandas - Format Timedelta as ISO 8601

To format Timedelta as ISO 8601, use the timedelta.isoformat() method. At first, import the required libraries −

import pandas as pd

Create a Timedelta object

timedelta = pd.Timedelta('4 days 11 hours 38 min 20 s 35 ms 55 ns')

Display the Timedelta

print("Timedelta...\n", timedelta)

Format as ISO 8601

timedelta.isoformat()

Example

Following 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('4 days 11 hours 38 min 20 s 35 ms 55 ns')

# display the Timedelta
print("Timedelta...\n", timedelta)

# format as ISO 8601
res = timedelta.isoformat()

# display the Timedelta as ISO 8601
print("\nFormat Timedelta as ISO 8601...\n", res)

Output

This will produce the following code

Timedelta...
4 days 11:38:20.035000055
