Checkpoint B In this checkpoint, we simulate groups of individuals playing the lottery. The final goal will be simulating two groups (a high-income group and a low-income group) and the movement of wealth across these. For example, we might represent one group of 5 individuals and their wealth by the list [2,3,4,5,6]. If this population plays (and loses) the lottery 2 times: • It could become [0,3,4,5,6], if the first individual played twice • Or it could become [2,3,4,4,5], if the last two individuals each played once • etc Continuing the example, scholarships might then award a total of $3 of awards to the population in the form of $1 scholarships. If the wealth had originally been [0,3,4,5,6], then: It could become[3,3,4,5,6], if the 1st individual got all three awards • Or it could become [0,4,5,5,7], if it was distributed equally among the 2nd, 3rd, and 5th individuals • etc We assume the lottery system is backed by a relatively huge pool of capital, so that scholarships are awarded no matter how many lottery winners there are. We also assume who plays the lottery and who benefits from scholarships will be random, at the individual-level. Later, at the population-level, we will select behaviors for our simulation based on social science research. The function generate_disparity_msg() returns a string summarizing the distribution of wealth. Here are examples of that analysis: highIncomeList lowIncomeList [2,3,4,5,6] [5, 6, 10, 14] [6,5,4,3,2] High income: 70% of wealth [1, 5, 7, 2] Low income: 30% of wealth [4, 10, 2, 5, 8] [2, 7] Wealth Distribution High income: 50% of wealth Low income: 50% of wealth msg = f"Decade (decade): High income group " +\ High income: 76% of wealth Low income: 24% of wealth Implementation Strategy Implement each function from the template following the description in their docstring: • sim_lottery() • award_scholarship () • generate_disparity_msg() For the messages returned by generate_disparity_msg(), adapt this fstring for your code: f"has (highIncome Percent:.0f) of the community's wealth. "+\ f"Low income group has {lowIncome Percent:.0f} * "+\ f" of the community's wealth."

Checkpoint B
In this checkpoint, we simulate groups of individuals playing the lottery. The final goal will be simulating two groups (a high-income group
and a low-income group) and the movement of wealth across these.
For example, we might represent one group of 5 individuals and their wealth by the list [2,3,4,5,6].
If this population plays (and loses) the lottery 2 times:
It could become [0,3,4,5,6], if the first individual played twice
Or it could become [2,3,4,4,5], if the last two individuals each played once
etc
Continuing the example, scholarships might then award a total of $3 of awards to the population in the form of $1 scholarships. If the
wealth had originally been [0,3,4,5,6], then:
It could become[3,3,4,5,6], if the 1st individual got all three awards
Or it could become [0,4,5,5,7], if it was distributed equally among the 2nd, 3rd, and 5th individuals
etc
We assume the lottery system is backed by a relatively huge pool of capital, so that scholarships are awarded no matter how many lottery
winners there are. We also assume who plays the lottery and who benefits from scholarships will be random, at the individual-level. Later, at
the population-level, we will select behaviors for our simulation based on social science research.
The function generate_disparity_msg() returns a string summarizing the distribution of wealth. Here are examples of that analysis:
highIncomeList
[2,3,4,5,6]
[5, 6, 10, 14]
msg=f"Decade
lowIncome List
[6,5,4,3,2]
[1, 5, 7, 2]
[4, 10, 2, 5, 8] [2, 7]
Wealth Distribution
High income: 50% of wealth
Low income: 50% of wealth
High income: 70% of wealth
Low income: 30% of wealth
High income: 76% of wealth
Low income: 24% of wealth
Implementation Strategy
Implement each function from the template following the description in their docstring:
sim_lottery()
• award_scholarship()
generate_disparity_msg()
For the messages returned by generate_disparity_msg(), adapt this fstring for your code:
High income group "+\
f"has {highIncome Percent:.0f) of the community's wealth. "+\
f"Low income group has {lowIncome Percent:.0f} "+\
f"of the community's wealth."
Again, by default, this project does not generate any interesting printed output. So, you should use one of these strategies in your work:
Use Python Tutor to do incremental development, focusing on one function at a time in isolation
Invent some of your own intermediate output, to get feedback while in develop mode
Submit your work to get feedback from unit tests
