Good day Everyone,
I am seeking help on two issues.
ISSUE 1:
Yesterday I posted a problem on this tiny script I wrote for temperature
conversion (as practice for a newbie). My error was pointed out to me that
there is a difference in upper and lowercase letters. After correcting that
error, I remember the tests I ran produced the correct outputs.
However, today I modified only the print instruction a little to try to print
out ℃ (in the second print clause). When I subsequently ran the script all the
outputs were executed from the if clause, even when I input other letters
(Please see below. I have removed the code to print degree C).
print('Enter C for Celsius to Fahrenheit or F for Fahrenheit to Celsius.')
unit = input('Enter C or F: ')
temp = int(input('Enter temperature: '))
if unit == 'C' or 'c':
f = temp * 9 / 5 + 32
print(str(temp) + ' C is equivalent to ' + '%.2f' % f + ' F.')
elif unit == 'F' or 'f':
c = (temp - 32) * 5 / 9
print(str(temp) + ' F is equivalent to ' + "%.2f" % c + ' C.')
else:
print('Please enter C or F in upper- or lowercase.')
The if statement block is to convert Celsius to Fahrenheit.
When I entered ‘C’ or ‘c’ and 100 for temperature, the output is correct: 100 C
is equivalent to 212.00 F.
The elif statement block is to convert Fahrenheit to Celsius.
When I entered ‘f’ or another letter, in this case ‘z’ and ‘g’, and 212 for
temperature, I got: 212 C is equivalent to 413.60 F.
I have looked at it many times today and could not see the error. Please advise.
ISSUE 2:
The second issue relates to the last statement above “I have looked at it many
times today and could not see the error”.
I was hoping that someone, perhaps one with pedagogical experience and
knowledge, could advise the following:
1. Is it possible that I may not have the right aptitude or mental
paradigm to do computer programming?
I think I don’t. My background is in finance, accounting and economics. When I
have difficulty in certain concepts in these fields I could figure it out
eventually, in reasonable time.
However, I am having difficulty learning it. I have been learning for a few
months already and I am not learning fast enough.
2. Nevertheless, I intend to keep learning and practicing, but wonder if
there is an effective way to get a breakthrough into the programming paradigm?
If so, kindly advise how and direct me to a suitable resource to do it.
Many thanks.
Best regards.
