# Noemi Cabrera # 18 November 2021 # In this lesson, I learned how to assign and modify a time object (variable) using the the time() function, # assign and modify a date object (variable) using the date() function, get the current local date by using # the date or datetime functions with .today(), assign and modify a datetime object (variable) using the datetime() # function, split a datetime object into separate time and date objects by using the indiviadula time and date # functions on the whole date, combine time and date objects into datetime objects using the combine method, and # display a datetime object as a formatted string using the strftime() function. # All of these functions are imported from the datetime module. # I didn't have any major difficulties in this lesson.

# In this code, the time function is imported from the datetime module. Then, it's used to display the time # given the values for hour, minte, second, and microsecond in order. from datetime import time # Time is 8:55:20.000500 PM (or 20:55:20.000500) t = time(20, 55, 20, 500) print(t)

# In this code, the time function is imported from the datetime module. Then, it's used to display the time # given the names and values values for hour, minute, second, and microsecond. However, these are not in order # because if the names are given the function will place them in order. from datetime import time # Time is 9:10:20.900000 AM (or 9:10:20.900000) t = time(minute = 10, hour = 9, microsecond = 900000, second = 20) print(t)

# In this code, the time function is imported from the datetime module. Then, it's used to display the time # given the the names and values for hour and minute.

# In this code, the time function is imported from the datetime module. Then, it's used to display the time # given the the name and value for hour.

# In this code, the time function is imported from the datetime module. Then, the names and values for hour, # minute, second, and microsecond are specified.

Each is stored in a variable. # The final time is printed. from datetime import time # assign a time variable t t = time(hour = 9, minute = 10, second = 43, microsecond = 100) # access each of the attributes separately h = t.hour # will be 9 m = t.minute # will be 10 s = t.second # will be 43 ms = t.microsecond # will be 100 print("The time is: ", h," hours ", m, " minutes", s, " seconds and ", ms, " microseconds" )

# In this code, the time function is imported from the datetime module. Then, the names and values for hour, # minute, second, and microsecond are specified. The orginal time is printed.
