Final answer:
The question involves writing a Python function that displays the current date and time without any formatting. The function 'display_current_date_and_time' utilizes the 'datetime.datetime.today()' method from the 'datetime' module to fetch and print the current date and time.
Step-by-step explanation:
The student is asking how to display the current date and time in Python using the datetime module. To accomplish this task, a function called display_current_date_and_time needs to be written.
This function will not take any parameters and will utilize the datetime.datetime.today() method to retrieve the current date and time. Below is a Python function that meets the requirements given in the question:
import datetime
def display_current_date_and_time():
current = datetime.datetime.today()
print(f"Current date and time: {current}")
This function first imports the datetime module, defines the function display_current_date_and_time, retrieves the current date and time using datetime.datetime.today(), and finally prints it out with the label "Current date and time:".
