Re: [Tutor] need a hint
I realize the code snippet was bad. It was meant to be pseudo code. I was
on my phone and far from pc. Anyway
I tried this:
already_seen = set()
for name in last_names:
if name in already_seen:
print("Already seen", name)
else:
already_seen.add(name)
I am not seeing a pattern in the output to give me a clue as to why it is
doing this. Also, it seems to be referencing chars when variable lastName
is an item in a list.

Re: [Tutor] need a hint
What I am having trouble with is finding a way to say: if lastName appears
more than once, print something.
I ran a bit of code:
For x in lastname
If lastname = udall
Print something
This prints x twice.
I think what I might be hung up on is understanding the ways that I can use
a loop. I know I need to loop through the list of names, which I have, and
set a condition dor the apppearance of a string occurring more than once in
a list but I don't know how to translate this to code. How do I say: if
you see it twice, do something?

You're currently doing this:
> senateInfo = {}
> senateInfo[lastName] = state
Instead of storing just a state in the dict you could store a list of
states e.g.:
senateInfo[lastName] = [state]
Then when you find a lastName that is already in the dict you can do:
senateInfo[lastName].append(state)
to append the new state to the existing list of states. You'll need a
way to test if a particular lastName is already in the dict e.g.:
if lastName in senateInfo:

[Tutor] need a hint
The following program works and does what I want except for one last
problem I need to handle. The program reads a txt file of senators and
their associated states and when I input the last name it gives me their
state. The problem is "Udall". There are two of them. The txt file is
read by line and put into a dictionary with the names split. I need a
process to handle duplicate names. Preferably one that will always work
even if the txt file was changed/updated. I don't want the process to
handle the name "Udall" specifically. For a duplicate name I would like
to tell the user it is not a unique last name and then tell them to enter
first name and then return the state of that senator.
Thanks

[Tutor] ideas?
Need a little help with finding a process for this: when a string of text is input, for example: abc def. I want to have each letter shift to the right one place in the alphabet. Thus.. abc def would be output as bcd efg. Any ideas on how to do this? ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
[Tutor] loop running twice?
def main():
goal, apr, deposit = getSavingsDetails()
determineMonthsTilSaved( goal, apr, deposit )
months = determineMonthsTilSaved(goal, apr, deposit)
summarize( months )
def getSavingsDetails():
"""
goal = float( input( "Principal sought? $" ) )
apr = float( input( "Interest rate? " ) )
deposit = float( input( "Deposit? $" ) )
"""
goal = 1000.0
apr = .05
deposit = 100
return goal, apr, deposit
def determineMonthsTilSaved( goal, apr, deposit ):
months = 0
saved = 0
totalInterest = 0.0
while saved < goal:
interest = saved * apr / 12
totalInterest += interest
saved += (deposit + interest)
months += 1
print( months, ("%.2f" % saved), ("%.2f" % totalInterest) )
return months
def summarize( months ):
print( "Saved! It took ", months // 12, "years and", months % 12,
"months." )
main()
When this is run it appears that determineMonthsTilSaved is running twice
before the loop ends. It is supposed to run until saved > than goal, but
look at the output. It runs again even after saved > goal. Help please?
