"Unorderable Types: Int() < Str()"

Why do I get Unorderable types: int() str() or '' not supported between instances of 'int' and 'str'?

The issue here is that input() returns a string in Python 3.x, so when you do your comparison, you are comparing a string and an integer, which isn't well defined (what if the string is a word, how does one compare a string and a number?) - in this case Python doesn't guess, it throws an error.

To fix this, simply call int() to convert your string to an integer:

int(input(...))

As a note, if you want to deal with decimal numbers, you will want to use one of float() or decimal.Decimal() (depending on your accuracy and speed needs).

Note that the more pythonic way of looping over a series of numbers (as opposed to a while loop and counting) is to use range(). For example:

def main():
    print("Let me Retire Financial Calculator")
    deposit = float(input("Please input annual deposit in dollars: $"))
    rate = int(input ("Please input annual rate in percentage: %")) / 100
    time = int(input("How many years until retirement?"))
    value = 0
    for x in range(1, time+1):
        value = (value * rate) + deposit
        print("The value of your account after" + str(x) + "years will be $" + str(value))

Python - TypeError: unorderable types: str() int()

Python cannot order str values and int values together.
In your example 99999 is an int value while all the other values are str values.

TypeError: unorderable types: str() = int()

The reason to this is that the function check_pb_ratio.get_price_book() returns a string, not an int. Python doesn't want to know the similarity between '1' and 1.
So, the way to fix it is: add int() or float() around check_pb_ratio.get_price_book()

TypeError: unorderable types: int() str()

In python3, input returns a string. You pass this string to your function directly and compare with integers obtained from random.choice. This is what happens:

In [535]: '1' > 2
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
<ipython-input-535-6857a5c3feea> in <module>()
----> 1 '1' > 2

TypeError: unorderable types: str() > int()

Conclusion: ints and strings are not comparable. You'll need to convert the input by calling the int function.

your_guess = int(input(...))

And then, it should work:

In [536]: 1 > 2
Out[536]: False

However, this solves only one problem. Every time you call your function, number is re-initialised with a new value each time, so that if you guess against a number and call the function again, you will be guessing against a totally different random number next time. You'll want to set numbers outside the function and then call the function, passing the guess and random number as arguments.

Why am I getting TypeError: unorderable types: str() int() in this code?

Sorry, I figured this out. For some reason, during the first run it saved the JSON key as a string. In the second run, it saved it as an integer. self.changes was printing as:

{'2': {'date': '2018-06-29 02:02:03', 'change': 'TEST'}, '1': {'date': '2018-06-29 01:07:37', 'change': 'TEST'}}

To fix that, I just changed

self.changes[count] = {'date': now.strftime("%Y-%m-%d %H:%M:%S"), 'change': change}

self.changes[str(count)] = {'date': now.strftime("%Y-%m-%d %H:%M:%S"), 'change': change}
