某个序列中预测基因并把序列提取出来，具体代码与解释如下：

#序列
seq = "ATGGAAGCAATCAAAGAAAATTGGAAAACTATCAAAGAAGCTGTCAGAAGAGAATACAGTCTTTCTGACATTTCTTATCATACATGGGTAGAACCTTTAGAATTTCACAATGTGGTAAATGATGTAGTAAGTATCATCATTCCCTCGGACCAGGCACATGCCCTGAATTATATTTCTTCCAAATATAAGAGTTTTTTTCAGGTAACCATCACCGAGATGTTTGATCATCCTTATGATATCAGCTTTATTTTCCCGGAAGAGATCCTGGTAGAGCATGAAGAGACCTGCATCCGTATTCCCATGCTCCCTGAGATCCGTTCCCTGAACCTGTCC"

import re
# 根据每个基因的起始密码子和终止密码子，进行基因的预测和报道！
for m in (re.findall('(ATG(...)+?(TAG|TAA|TGA))', seq)):
  print('gene {}'.format(m[0]))

运行结果为：
