input("Press Enter to stop...")

stop = datetime.now()

month = stop.strftime("%B")

day = stop.strftime("%d")

hours = stop.strftime("%I")

minutes = stop.strftime("%M")

am_pm = stop.strftime("%p")

print("Stop time: ",month,day,"at",hours,":",minutes,am_pm)

elapsed_time = stop - start

new_days = elapsed_time.days

new_minutes = elapsed_time.seconds // 60

new_hours = new_minutes // 60

new_minutes = new_minutes % 60

print("Time elapsed: ")

if new_days > 0:

print("days:",new_days)

print("hours:", new_hours, ", minutes:", new_minutes)

if __name__ == "__main__":

Numerical and categorical. Then, each category is divided into two subcategories: discrete or continuous for numeric variables, and nominal or ordinal for categorical variables.

In their investigations, psychologists frequently use several dependent variables. The main justification for this is that it makes it simple for them to quickly and cheaply respond to more study inquiries.

A naming scale is one in which variables are merely “named” or labelled, without regard to their order. Beyond just identifying them, the variables on an ordinal scale have a precise order.
