'How to create a new .txt with lines from another .txt
I have a document with this structure (it's large, more than 20000 lines)
@A00627:308:H227VDSX3:1:1363:9616:15013 1:N:0:TTCTGCAG+TTCCGGTA
GATACATCGCCATCCGAATTCCACTCCGGTACAATGGCTTGGTGACGGGTATGAGGGCGAAGGGCATCATTGCGATTTGCTGGGTGCTGTCATT
+
FFFFFFFFFFFFFFFFFFFFFFFFFFFFFF:FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF
@A00627:308:H227VDSX3:1:1568:1362:27430 1:N:0:TTCTGCAG+TTCCGGTA

@A00627:308:H227VDSX3:1:2375:11198:6511 1:N:0:TTCTGCAG+TTCCGGTA
CTGGCTTCTGCGCTGCCTGCCATGGCTGCCTCTTCTTCGCCTGCTTTGTCCTGGTCCTCACGCAGAGTTCCATCTTCAGCCTCTT
+
FFFFFFFFFFFFFFFFFFFFFFFFFFFFFF:FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF
And I want to create a new document with part of the lines... Such as:
>1
GATACATCGCCATCCGAATTCCACTCCGGTACAATGGCTTGGTGACGGGTATGAGGGCGAAGGGCATCATTGCGATTTGCTGGGTGCTGTCATT
>2
ACTGGCTTCTGCGCTGCCTGCCATGGCTGCCTCTTCTTCGCCTGCTTTGTCCTGGTCCTCACGCAGAGTTCCATCTTCAGCCTCTTGGCT
>3
CTGGCTTCTGCGCTGCCTGCCATGGCTGCCTCTTCTTCGCCTGCTTTGTCCTGGTCCTCACGCAGAGTTCCATCTTCAGCCTCTT
....
I think that this it's easy, but I am very new in coding, how should I do it?
