Python programming
Please I need help writing a function named right_justify that takes a string named s as a parameter and prints the string with enough leading spaces so that the last letter of the string is in column 70 of the display.
>>> right_justify('monty')
monty
Hint: Use string concatenation and repetition. Also, Python provides a built-in function called len that returns the length of a string, so the value of len('monty') is 5.
Exercise 3.2. A function object is a value you can assign to a variable or pass as an argument. For example, do_twice is a function that takes a function object as an argument and calls it twice: def do_twice(f): f() f() Here's an example that uses do_twice to call a function named print_spam twice. def print_spam(): print('spam') do_twice(print_spam)
a. I have to write an example into a script and test it.
b. Modify do_twice so that it takes two arguments, a function object and a value, and calls the function twice, passing the value as an argument.
c. Copy the definition of print_twice from earlier in this chapter to your script.
d. Use the modified version of do_twice to call print_twice twice, passing 'spam' as an argument.
e. Define a new function called do_four that takes a function object and a value and calls the function four times, passing the value as a parameter. There should be only two statements in the body of this function, not four. Solution: http: // thinkpython2. com/ code/ do_ four. py .
Exercise 3.3. Note: This exercise should be done using only the statements and other features we have learned so far.
a. I have to write function that draws a grid like the one shown in your text on page 27.
Hint: to print more than one value on a line, you can print a comma-separated sequence of values: print('+', '-') By default, print advances to the next line, but you can override that behavior and put a space at the end, like this: print('+', end=' ') print('-')
The output of these statements is '+ -' on the same line. The output from the next print statement would begin on the next line.
b. I have to write function that draws a similar grid with four rows and four columns. Solution: http: // thinkpython2. com/ code/ grid. py .
