Python Pandas - Format the Period object and display the Time with 24-Hour format

To format the Period object and display time in 24-hour format, use the period.strftime() method with the %H parameter. The %H format code represents hours in 24-hour format (00-23).

Creating a Period Object

First, let's create a Pandas Period object with a specific date and time ?

import pandas as pd

# Create a Period object with second frequency
period = pd.Period(freq="S", year=2021, month=9, day=18, hour=17, minute=20, second=45)

print("Period object:")
print(period)

Period object:
2021-09-18 17:20:45

Formatting with 24-Hour Time

Use strftime() with %H to extract the hour in 24-hour format ?

import pandas as pd

period = pd.Period(freq="S", year=2021, month=9, day=18, hour=17, minute=20, second=45)

# Format hour in 24-hour format
hour_24 = period.strftime('%H')
print("24-hour format:", hour_24)

# Compare with 12-hour format
hour_12 = period.strftime('%I %p')
print("12-hour format:", hour_12)

24-hour format: 17
12-hour format: 05 PM

Common Time Format Codes

Here are useful format codes for time formatting ?

import pandas as pd

period = pd.Period(freq="S", year=2021, month=9, day=18, hour=17, minute=20, second=45)

print("Hour (24-hour):", period.strftime('%H'))
print("Hour (12-hour):", period.strftime('%I'))
print("Minute:", period.strftime('%M'))
print("Second:", period.strftime('%S'))
print("Full time (24h):", period.strftime('%H:%M:%S'))
print("AM/PM:", period.strftime('%p'))

Hour (24-hour): 17
Hour (12-hour): 05
Minute: 20
Second: 45
Full time (24h): 17:20:45
AM/PM: PM

Format Codes Summary

Conclusion

Use strftime('%H') to format Pandas Period objects and display hours in 24-hour format. This method provides flexible time formatting with various format codes for different time components.
