[FIXED] I am trying to append a line of Text to a list

Issue

Seq = []
Head = []

for line in range (0, len(text)):
   if line in '>':
      Head.append(line)
   else:
      Seq.append(line)

I am trying to append the header of FASTA sequences and the nucleotide sequence and separate them on a list. I don't know how to say that if line has '>', add to Head, else add to Seq

Solution

The line: line in '>' is testing whether line can be found inside the string '>'. You need to swap them around to '>' in line. This will test if the string '>' can be found inside line. If you are trying t test if the first character of line is '>', use 'line[0] == '>'.

Also when using range the start will default to zero so you could say for x in range(len(text))

Final code:

Seq = []
Head = []

for line in range (len(text)):
   if '>' in line:
      Head.append(line)
   else:
      Seq.append(line)
