One solution, please verify:
def group_seq(seq):
seq_out = []
skip = 0
seq_len = len(seq)
for i,char in enumerate(seq):
if skip > 0:
skip = skip - 1
continue
if seq_len <= i+1:
seq_out.append(char)
break
if seq[i+1] == '/':
seq_out.append(char+seq[i+1]+seq[i+2])
skip = 2
else:
seq_out.append(char)
return seq_out
if __name__ == "__main__":
seq = "AT/CG"
print seq, group_seq(seq)
seq = "A/UT/CG"
print seq, group_seq(seq)
seq = "A/UT/CG/A"
print seq, group_seq(seq)
seq = "AT/CGAAA"
print seq, group_seq(seq)
seq = "AT/CGAAG/CG/TCA"
print seq, group_seq(seq)
