With the help of Access users can successfully manage valuable information by saving it easily for future reporting it , and analysis.In access users can have access to organized data in their database with minimal effort.
You can enter the data and you can select which data you want and use queries for that accordingly for example:- joins,select statements etc.
A program that repeatedly prompts a user for integer numbers :
biggest = none
smallest = none
while True:
input = raw_input(“Enter a number:”)
if(input == “done” break
try:
number = float(inp)
except ValueError:
print “Please enter only numbers”
else
if smallest is None:
smallest = number;
biggest = number;
elif number < smallest:
smallest = number
elif num > largest:
largest = number
Print “Greatest is “, biggest
Print “Smallest is”, smallest
In this program an input is obtained, if it is equal to the word “done”, then the program stops b printing greatest and smallest number in the given input.
If invalid inputs are given then user is prompted to enter valid number. Otherwise the value of smallest and greatest are calculated according to the input using if-else construct.
Answer:
Revisiting "Build a Tower"
Recall in the last section how we made Karel make a tower of tennis balls. We told Karel to move() and turnLeft() and putBall() until we had a tower. At the end of the program, Karel was still at the top of the tower, like as in the picture below.
Stuck at top
Suppose that now we want Karel to come back down from the top of the tower. The first thing we need to do is get Karel facing in the right direction. One way to do this is to tell Karel
turnLeft();
turnLeft();
turnLeft();
And then tell Karel to
move();
move();
move();
back to the bottom of the tower.
However, telling Karel to turnLeft() three times is not very readable. That's a lot of writing when all we really want is to tell Karel to "turn right."

Hopefully it would help.
