2023.9.13 I understand the Data Types within "Number Words" from learning and teaching Java. The planning.md was straight forward. Was my return for each function correct? Am I to used " " for the string of text. Within some of your discussions in Discord, you had mention to checkout using ChatGPT. I wouldn't sign on to ChatGPT because it wanted your phone number. Instead, I used Bing Chat after signing into my Microsoft account. Wow!!! I found it interesting with the extensive explanation of information it provides to solve a problem. I didn't use it for the answers. AI is very scary if not used in a responsible manner. Yes, the numberwords.py had all the answers, but I found it valuable because of how you wrote out the digit numbers for the "else" and "return". In do understand this. The test_numberwords.py file completely passed with the test_cases.

# Planning Number Words
|
|
|
|
Before you start programming, do some planning here on how you will break down
|
|
this problem. Here's a hint: if you start by writing functions for smaller numbers,
|
|
you will find that these functions help you with the larger numbers. For each of
|
|
the cases below, explain how you would turn a number into a string. Feel free to
|
|
write in sentences or in pseudocode (pseudocode is a sort of "casual programming"
|
|
where you're almost writing in code, being pretty specific without worrying about
|
|
syntax. For each case below, assume the integer is zero or more--don't worry about
|
|
negative integers.
|
|
|
|
## Integers under 10
|
|
(This one is done for you!)
|
|
For an integer less than ten, you need to know the name of each digit, and look it
|
|
up. You could use a big if/else statement like:
|
|
|
|
```
|
|
if number == 0:
|
|
return "zero"
|
|
elif number == 1:
|
|
return "one"
|
|
elif number == 1:
|
|
return "two"
|
|
```
|
|
|
|
A cleaner way to do this would be to make a list of digit names, from zero to nine.
|
|
Then you could just look up a digit's name:
|
|
|
|
```
|
|
digit_names = [
|
|
"zero", "one", "two", "three", "four",
|
|
"five", "six", "seven", "eight", "nine"
|
|
]
|
|
return digit_names[number]
|
|
```
|
|
|
|
## Integers under 20
|
|
If the integer is under 10, then use the procedure described above.
|
|
Otherwise, ... (this is where you take over!)
|
|
|
|
# Define the integer to string
|
|
# Could use if else
|
|
# elif should be returned to "zero" or "Number is greater than or equal to 20."
|
|
# ??Not sure
|
|
|
|
def int_under_20_to_str(number):
|
|
if number <20:
|
|
return str(number)
|
|
elif number >= 20:
|
|
return "Number is greater than or equal to 20."
|
|
|
|
## Integers under 100
|
|
def int_under_100_to_str(number):
|
|
if number < 100:
|
|
return str(number)
|
|
elif number >= 100:
|
|
return "Number is greater than or equal to 100."
|
|
|
|
## Integers under 1000
|
|
def int_under_1000_to_str(number):
|
|
if number < 1000:
|
|
return str(number)
|
|
elif number >= 100:
|
|
return "Number is greater than or equal to 1000."
|
|
|
|
## Integers under 1000000
|
|
def int_under_1000000_to_str(number):
|
|
if number < 1000000:
|
|
return str(number)
|
|
elif number >= 100:
|
|
return "Number is greater than or equal to 100."
|
|
|
|
## Negative integers down to -1 million
|
|
We won't deal with negative integers in this problem set,
|
|
but how would you deal with a negative integer, using the
|
|
functions above?
|
|
|
|
# You can use the negative integer range from -1 to -1000000
|
|
if number < 0:
|
|
if number > -1000000:
|
|
elif number >= 0:
|
|
elif number >= 1000000:
|
|
|
|
# Is this what you are looking for coding the define functions?
