Answers should be legal Python code, including indentation. Use the underscore _ to show a space.

Special functions: print(), range(), sqrt(), str()

Use a loop to print 20 lines with a line number and the word "dumdum". For example, line 1 should be "1: dumdum", line 2 would be "2: dumdum", etc.

Use: variables, loops, str()[2]

Use a loop to create a string that has 15 "C" characters

Use: variables, loops[2]

Assume you have a list of numbers Z. Create a new variable that is equal to sum of all the numbers in Z.

Use: variables, loops[2]

Test Using:
Z = []
Z = [1,1]
Z = [14,31,47]

A factorial of a number is all the numbers from 1 to that number multiplied together, so 4! = 1x2x3x4. Write code using a loop to calculate 58!

Use: variables, loops, str()[2]

Assume you have a list of numbers Q. Write code to count how many numbers in the list are smaller than or equal to than 5

Use: variables, loops, if[3]

Test Using:
Q = []
Q = [5,0,25]
Q = [1,47,69]

Assume you have a non-empty list Z. Create a new variable that is equal to the first element in the list.

Use: variables[1]

Test Using:
Z = [1]
Z = ['a','b','c']
Z = [72,56,55]

Use a loop to add the numbers from 4 to 30

Use: variables, loops[2]

Assume you have 2 lists of numbers with 14 elements each: Q and F. Add the 8th elements of the lists together.

Use: variables[1]

Test Using:
Q = [1,2,3,...,14], F = [1,2,3,...,14]
