Python | Pandas Period.asfreq

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 Period.asfreq() function is used to convert Period to desired frequency, either at the start or end of the interval.

Syntax : Period.asfreq()



Parameters :
freq : string
how : Start or end of the timespan

Return : resampled : Period

# importing pandas as pd
import pandas as pd
  
# Create the Period object
prd = pd.Period(freq ='S', year = 2000, month = 2, day = 22,
                        hour = 8, minute = 21, second = 24)
  
# Print the Period object
print(prd)

Output :

Now we will use the Period.asfreq() function to change the frequency of the prd object to ‘Daily frequency’.
