"module 'babel' has no attribute 'dates'" when trying to format time and date

I have written this function to format time and date in my Flask app with Babel:

import babel
from flask import Flask

app = Flask(__name__)

def format_datetime(value, format='medium'):
    if format == 'full':
        format = "EEEE MMMM, d, y 'at' h:mma"
    elif format == 'medium':
        format = "EE MM, dd, y h:mma"

    print(format)    
    return babel.dates.format_datetime(date, format)

app.jinja_env.filters['datetime'] = format_datetime

strTime = '2021-01-07 12:13:07'
print(format_datetime(strTime))

But when I run this it raises this exception:

 Traceback (most recent call last):   
    File "C:\Users\user\Desktop\timedateTest\timepy.py", line 26, in <module>
     print(format_datetime(strTime))   
    File "C:\Users\user\Desktop\timedateTest\timepy.py", line 18, in format_datetime
     return babel.dates.format_datetime(date, format) AttributeError: module 'babel' has no attribute 'dates'

What I am doing wrong?

Try changing:

import babel

to:

from babel.dates import format_date, format_datetime, format_time
