import pendulum

dt = pendulum.datetime(year=2021, month=1, day=1, hour=8, minute=20, second=30)

print('to_date_string() result:')
print(dt.to_date_string())

print('\nto_formatted_date_string() result:')
print(dt.to_formatted_date_string())

print('\nto_time_string() result: ')
print(dt.to_time_string())

print('\nto_datetime_string() result:')
print(dt.to_datetime_string())

print('\nto_day_datetime_string() result:')
print(dt.to_day_datetime_string())

Format DateTime string using formatter format() and strftime() method

We also can use format() and strftime() methods to format string as below. 

import pendulum

dt = pendulum.datetime(year=2021, month=1, day=1, hour=8, minute=20, second=30)

print(dt.format('dddd Do [of] MMMM YYYY HH:mm:ss A'))
print(dt.format('YYYY-MM-DD HH:mm:ss'))
print(dt.format('[Today is] dddd'))

print(dt.strftime('%Y-%m-%d %H:%M:%S %Z%z'))
print(dt.strftime('%I:%M:%S %p'))
The program output.
