Would you take a job that goes for 14 days, where on the first day you make 1 cent, on the second day you double to 2 cents, on the third day you double this to 4 cents and so on?

The average distance between Earth and Sun is about 150 million kilometers (93 million miles). Write a Python program the calculates the speed (km/hr or miles/hr) the Earth has around the Sun.

The speed of light is 300,000 kilometers per second (186,282 miles per second). Assume the Earth-Sun distance is 150 million kilometers (93 million miles). How long does light from the Sun take to reach the Earth?

Use the Python module decimal to show that the result of 1/61
has a period of 60 (repeats every 60 digits),
also every digit appears 6 times in the period.

Develop an mp3 player using the pygame's mixer module with a GUI interface with buttons for browsing the file (Filedialog module of Tkinter) and other buttons for play, pause and stop. You can also go ahead with a time display as a label to measure the time for which the song has been playing. Later additions may also include some pictures or a song queue like a playlist and other fun stuff. For MP3 and MIDI playing using pygame refer to vegaseat's code as posted in the thread

A football league simulator with 10 teams each of 15 players. Simulate each match in a randomly generated schedule and decide the winner using the attributes of the team and a probability function which basicall decides the winner or if the game is draw on an equal basis for teams with equal strength. Make the league more funky with your own imaginative teams and imaginative players. Expand the game with many such repetitions of the schedule and finally declare a winner based on the points each team has scored.

A small game like a point and shoot adventure using the Pygame module of Python.
Make enemy characters appear at random in certain spots in your screen(say a building) and pick them off with your awesome shooting skills!

Here's one toy script I'm going to write when I'm ready: convert a number expressed in decimal digits to a number expressed in a standard way in English words, and vice-versa. (For example, convert 2,733.89 to "two thousand, seven hundred and thirty-three point eight nine" and vice-versa.)

Write a Python program that goes through a given text and gives the number of the longest words and the average length of all words.

good motivation

This is off the top of my head and probably buggier than anything:

#! usr/bin/env python3

import string

# assume variable "text" has already been defined

text_set = set(text.slice())
word_lengths = set(len(text.set[x]) for text_set)
# I forget the method for the largest number; call it "largest"
longest_word = word_lengths.largest()

text_list = [text.slice()]
word_lengths_list = [len(x) for x in len(text_list)]
total_length =+ word_lengths_list[x] for len(word_lengths_list)
average_word_length = total_length / len(word_lengths_list)


# ouptut longest_word and average_word_length

Calculate the area of a regular polygon given side_length s and number of sides n.

Also if you had
s = 0.01
n = 1000
which approaches a circle. What would the radius of that circle be?

Here is an answer that contains no syntax errors or exceptions but appears to contain semantic errors. Maybe someone could help out:

#! /usr/bin/env python3

def calculate_area(n, s):
    """calculate area of regular polygon given external input n = number of sides
       and s = length of each side; returns the area as a float"""

    from math import tan

    return n * s ** 2 / 4 / tan(180 / n)

To add to the comment of Gribouillis: to convert from degrees to radians use math.pi/180 For an angle of 90° that would give Math.pi/2.

Write a Python program that calculates the area or surface area of a number of well known shapes like hexagon, cube, pyramid, circle, cone, sphere, cylinder, and so on.

Also, remember that trig functions use angles in radians. The math module helps with ...
math.degrees(x) converts angle x from radians to degrees
math.radians(x) converts angle x from degrees to radians
