Anyone at SFU right now?

So CMPT guys.... Python Gods.....

I'm trying to count the number of LETTERS/CHARACTERS in a string and not its numbers/special characters.

So in a string like "abc132add" it would count 6 (only the letters) any idea how to do this?

I'm not looking for a position thing because the strings can be different.

Look for asci characters and see which of them are the letters. Then if the asci is between that range, count it as a letter

I think that's too advanced? I was going to do some variation of len(st) or st.count(abcd...).

But neither of those work....

Oh god it's been a long time since I took cmpt120... but can't you use isdigit and isalpha?

ex.

"a".isalpha() should return true, and "a".isdigit() should return false...

So after you define your input...

count=0
for char in input:
if isalpha(char):
count +=1
return count



Otherwise I think Messer is right in that you can use string.ascii too.. but I don't have python on this computer to play around with lol.

Yep! We're up there today as well with that autographed Burrows jersey prize.

Thanks though!

Anyone know any good cmpt tutors?

Really? What does it return? So fail...

def main():
<I>sentence = input('Enter a sentence: ')
<I> Stats(sentence)

def Stats(input):
<I>print('Letters:', letter(input))

def letter(input):
<I>count=0
<I>for char in input:
<I><I> if isalpha(char):
<I><I><I> count += 1
<I> return count

Sorry... I tried installing python but I don't have administrator rights so it won't let me lol. Indents don't seem to show lol. where <I> represents an indent

I'm not looking for a position thing because the strings can be different.

So here's a pseudocode I came up with for this:

alphabet = letters of alphabet (lowercase and uppercase)
intizalize count to 0

for letters in string //Check each character in string

if letters in alphabet //if character is in the alphabet than count + 1

count = count + 1

return count

Spoiler!

def countLetters (st):
count = 0
alphabet = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVW XYZ"

for letters in st:

if letters in alphabet:

count += 1

return count

print countLetters('12abc!#456') --> 3
print countLetters('abc123de') --> 5
print countLetters('abc143abc') --> 6

Thanks for the effort all.

Assignment closed already. I'll post up answers once they are received.

problem with isalpha(char) is that it is supposed to be string.isalpha();, so you would need to do

for i in range 1 to len(string)
if string[i-1].isalpha()
count += 1;

Used to be in bus, then realize it's a pointless degree unless you're in accounting. So I switched to a BSc. degree

Damn why are you guys so early? Mine is on the 21st. Is it because you guys are in 4th year, a lot of units accumulated, or high GPA?
