If user is not in users:

$4\mathrm{.}1.$ Print out a message to let the customer know that he$/$she doesn$$t have an account with

the Bank.

$4\mathrm{.}2.$ Print out another message to ask the customer if he$/$she would like to have an account

with the bank. Convert the input to lower case with casefold$()$ or lower$()$ function.

$4\mathrm{.}2\mathrm{.}1$ If the first letter entered is not equal to $$y$,$ print out an inspiring message to

encourage the customer to come back again, then exiting the program.

$4\mathrm{.}2\mathrm{.}2$ else ask the customer if he$/$she would like to enter $1$ to create a pin or enter $2$

to have the system create a new pin

$4\mathrm{.}2\mathrm{.}2\mathrm{.}1.$ The user gets $3$ chances to pick a pin between $1$ to $9999.$

$4\mathrm{.}2\mathrm{.}2\mathrm{.}2.$ If the customer would like to have the system create a new pin, the system will

randomly create a pin between $1$ to $9999$

$4\mathrm{.}2\mathrm{.}3$ Save the new username and pin to users dictionary when the pin is successfully

created.

users$[$user$]=$ pin

$4\mathrm{.}2\mathrm{.}4$ After the pin is created, display the following message:

$4\mathrm{.}2\mathrm{.}5$ Clear the output screen once the pin is created with os$.$system function.

$5.$ Continue with the code we created in PE$1$ to ask the user $($the existing user or the new

user$)$ to enter the pin and make transactions. Please note: we will not code an else block

for the if statement coded in step $4.$

$5\mathrm{.}1.$ In the users dictionary, now the pin is saved as an integer not a string. After we ask a

bank customer to

selection $=$ input$(\text{'}$Enter pin or x to exit application: $\text{'}).$casefold$()$

$5\mathrm{.}2.$ We first check to see if selection $==$x$.$ If that is true, use the keyword break to exit

the while loop if x is entered, as we coded in PE$1.$

$5\mathrm{.}3.$ If the bank customer entered the pin, we need to convert that to an integer since all

inputs collected from console are string.

Here is how we coded in PE$1$:

elif selection $!=$ pin :

We will change that to the following in PE$2$:

elif int$($selection$)!=$ users$[$user$]$ :
