Can anyone tell me what is the error in this program I want to produce letter F with this program.

Question

shape = "@"
no_of_lines = 8
current_line = 1
while current_line <= no_of_lines :
if current_line == 1 or 4:
print(shape * 10)
else:
print(shape * 2)

current_line += 1

Answer 1

(1, 4) is a tuple. That's a datatype containing more than one value.

x in (1, 4) checks if the value of x is in that tuple, in other words: if x is either 1 or 4.

You wrote x==1 or 4.

This means: Either x equals 1, or 4 is true.

Get that? You're just checking if 4 is true, you aren't checking, if it equals x.

You could have written x==1 or x==4 instead - that way you'd be checking for both.

x in (1, 4) is shorter though.

Answer 2

Change line 5 to this:

if current_line in (1, 4):

(Do you understand what went wrong?)
