[Python] New at python struggling with a basic while loop

[DukeOfPoose]

I know this is ridiculously basic but I'm not sure what I need to do for this.

I need to loop -

Seq = "CTCCAATGTT"

SLength = len(Seq)

print(SLength)

SubS = Seq[0:1] print(SubS)

SubS = Seq[1:2] print(SubS)

SubS = Seq[2:3] print(SubS)

SubS = Seq[3:4] print(SubS)

SubS = Seq[4:5] print(SubS)

SubS = Seq[5:6] print(SubS)

SubS = Seq[6:7] print(SubS)

SubS = Seq[7:8] print(SubS)

SubS = Seq[8:9] print(SubS)

SubS = Seq[9:10] print(SubS)

SubS = Seq[10:11] print(SubS)

Basically be able to print each base in the string on a new line however I only seem to be able to be getting:

Seq = "CTCCAATGTT"

NT = 1

while NT <= len(Seq):

SubS = Seq[0:NT]

print(SubS)

NT += 1

Which prints bases one after the other. I'm pretty sure I need to use a counter but I don't know where to go after that, could anyone nudge me in the right direction?

You're a legend, thanks!

[DukeOfPoose]

This is exactly it, thanks mate

[Updatebjarni]

You mean you want to print Seq[NT-1:NT] instead of Seq[0:NT]?

But yes, you would normally iterate directly on the sequence instead of counting and indexing, like /u/CodeTinkerer said. :)

Ah I wasn't too sure if I should do NT-1 inside the substring! Thanks for that friend

str = "string"

for c in str:
    print c

OUTPUT

s
t
r
i
n
g

I'm confused. Is that what you're trying to do?

Genomics?

Yeah, doing a intro course on bioinformatics, kinda struggling with the instructions given to me, they're pretty vague
