It seems like if statement doesn't execute or may be because i have made some mistake.
I tried,
ends = line.endswith('/')
if (line.startswith(' ') and ends == True)
But doesn't work. If statement doesn't run
count = 0
for line in f1:
if (line.startswith(' ') and line.endswith('/')):
count = count + 1
continue
elif line.startswith((' ', ' ', '//')):
continue
else:
if (count == 0):
f2.write(line)
count = 0
If line starts with '//' or single or double spaces, those lines should not be printed (condition 1). Also, if a line starts with double space and ends with '/' and next line doesn't satisfy condition 1, it should no be printed. Lines without condition 1 must be printed
Input:
//abcd
abcd/
This line should not be printed
This has to be printed
Expected Output:
This has to be printed
Actual output:
This line should not be printed
This has to be printed
Lines generated by iterating through a file object always end with a newline character (unless it's the last line of the file and the file does not end with a trailing newline character). You can apply rstrip to the line before you use endswith to test if a line ends with a certain character. Also, you should reset counter (with count = 0) outside of the if (count == 0): block; otherwise the statement would never run:
from io import StringIO
f1 = StringIO('''//abcd
abcd/
This line should not be printed
This has to be printed
''')
f2 = StringIO()
count = 0
for line in f1:
if (line.startswith(' ') and line.rstrip().endswith('/')):
count = count + 1
elif not line.startswith((' ', ' ', '//')):
if (count == 0):
f2.write(line)
count = 0
print(f2.getvalue())
This outputs:
This has to be printed
