There is a S :)
and otherwise There is no S :’(
Try also with “candy”, “multimedia” and “Sandra”.

Year is a leap year, if it can be divided by 4. However, if it is divided by 100, it is a leap year only if it can also be divided by 400.
Create a program, which checks if a letter is a vowel. It should look like this
a is a vowel
A is a vowel
c is NOT a vowel
Define a new number variable and choose a value for it. If the variable + 1 is can be divided by three, increase the variable by two. Test by printing the final value of the variable and varying the initial value of that same variable.
Compute the sum of 1 + 2 + …. + 100 using a loop structure
Matti tries to calculate 1 2 3 … 11.
However the following program does not work, figure out why. Do not use the computer to solve this, but work with paper and pen. Type it down to the computer to ensure you’ve fixed it
fraction = 0
for current in range( 1 , 12 ):
fraction * current
fraction = current
print fraction
Matti also tries to compute the sum from 1 to 1000, but it does not work. Figure out why and fix it. Do not use computer.
sum = 0
for i in range( 1, 1001 ):
sum = i
i = i + 1
print i
How many of the numbers 1, …, 10000 can be divided by four?
Correct: 2500
Correct: 16668333
So, it should look something like this
