Python for循环只运行一次？

Question

该脚本将根据csv中的数据库查询包含物种名称的csv，如果两者都在，则返回。问题是，尽管它仍在阅读所有术语以进行精细搜索，但它只是在搜索第一个术语。i、 e.如果我在“p中的行”之前打印物种L，所有物种名称都会正确返回

from pathlib import Path
import os
import csv

p = csv.reader(open('Paldat.csv','r',newline=''), delimiter=',')

with open('newsssssss.csv','r',newline='\n')as r:
    for line in r:
        taxons=line.split(',')
        no = ['\r\n']
        noo = ['\n']
        
        if taxons == no:
                continue
        elif taxons == noo:
                continue        
        else:
            speciesl = []
            for val in taxons:
                val = val.replace('\n','')
                speciesl.append(val)
            g=speciesl[0].lower()
            if len(speciesl) < 2:
                continue
            else:
                s=speciesl[1].lower()
        for row in p: #This loop seems to be the issue
                genus = row[0].lower()
                species = row[1].lower()
                if g == genus and s == species:
                    print('Perfect match')
                    print(g)
                elif s == species:
                    print(speciesl)
                    print('Species found')
                else:
                    continue
        else:
                continue
