Q about .count() python

Question

Hello we have simple code for counting symbols inside string.
s = input()
count = s.count(f)
print(count)

Q. Why i cant put this inside print(). Like.
s = input()
print(s.count(f))

Why second code end with error? We can make math inside print why can't use methods?

Answer 1

Q about what "f" is.
i did not get an error. link your code.

Answer 2

You need to either define f in a variable, or if you are looking for the letter f in your string it must be enclosed in quotes:

print(s.count("f"))

Answer 3

Alexandr Meskin ,

what did you mean by saying `symbols` to count? >>> is it punctuation like `!"#$%&'()*+,-./:;<=>?@[\]^_`{|}~` ?

in this case we can count anything except *alphanumericals* and *spaces*, because this is more efficient than counting for each of the symbols

using a for loop:

for char in text:text = 'a34Z& eK9$.;5 xx' # has 4 symbols
counter = 0
for char in text:
if not (char.isalnum() or char.isspace()):
counter += 1
print(counter)

Answer 4

where did the “f” come from?

Answer 5

We can do whatever we want inside the print function. Its not about it.

Answer 6

As mang have pointed out here, what do you exactly refer “f” to? Liek what is the context? Provide full code.
