如何迭代多个列表并仅在存在时打印出来

Question

我试图迭代几个列表，并找到一个项目是否存在于其他列表中。 这是我的密码：

with open("Busca1.txt", "r") as f, open("CELLO1.txt","r") as f1, open("PSORT.txt","r") as f2, open("results","w+") as of :
    file_in = f.readlines()
    file_in1 = f1.readlines()
    file_in2 = f2.readlines()
    file_in3 = f3.readlines()
    for line in file_in:
        temp = line.split()
        ID_busca = temp[1]
    for line in file_in1:
        temp2 = line.split()
        ID_cello = temp2[1]
    for line in file_in2:
        temp3 = line.split()
        ID_psort = temp3[1]

        all = [i for i in ID_busca if i in ID_cello + ID_psort]
        print all

我得到的是：

['Y', 'P', '_', '2', '0', '7', '6', '8', '4', '.', '1']
['Y', 'P', '_', '2', '0', '7', '6', '8', '4', '.', '1']
['Y', 'P', '_', '2', '0', '7', '6', '8', '4', '.', '1']
['Y', 'P', '_', '2', '0', '7', '6', '8', '4', '.', '1']
['Y', 'P', '_', '2', '0', '7', '6', '8', '4', '.', '1']
['Y', 'P', '_', '2', '0', '7', '6', '8', '4', '.', '1']
['Y', 'P', '_', '2', '0', '7', '6', '8', '4', '.', '1']
['Y', 'P', '_', '2', '0', '7', '6', '8', '4', '.', '1']
['Y', 'P', '_', '2', '0', '7', '6', '8', '4', '.', '1']
['Y', 'P', '_', '2', '0', '7', '6', '8', '4', '.', '1']
['Y', 'P', '_', '2', '0', '7', '6', '8', '4', '.', '1']
['Y', 'P', '_', '2', '0', '7', '6', '8', '4', '.', '1']
['Y', 'P', '_', '2', '0', '7', '6', '8', '4', '.', '1']
['Y', 'P', '_', '2', '0', '7', '6', '8', '4', '.', '1']
['Y', 'P', '_', '2', '0', '7', '6', '8', '4', '.', '1']
['Y', 'P', '_', '2', '0', '7', '6', '8', '4', '.', '1']


So the item is split by a letter and it seems to be printed out and one item seems to be several times. 

以下是文件示例：

有人能帮我把代码弄到我需要的地方吗？ 如果在所有当前列表中都存在，我想打印YP*********代码

谢谢

Answer 1

你需要修正你的逻辑。我不知道你是怎么做到的。首先，引用一个不存在的文件f3；你有一个of别名，你打算在那里？ 其次，给定的输出不是来自发布的代码。请确保你的问题陈述完全准确

至于预期的操作，请查看循环形式：

for line in file_in:
    temp = line.split()
    ID_busca = temp[1]

仔细阅读文件的每一行，将其拆分，提取ID号，然后用最新的ID号覆盖以前的ID号。当您退出这个循环时，ID_busca是一个简单的字符串，仅为最后一个ID号。当你到达第二个循环的末端时，你有

ID_busca = "YP_207731.1"
ID_cello = "YP_207190.2"

现在迭代PSORT，依次提取每个ID。让我们看看第一个：

ID_psort = "YP_008914846.1"

现在，您的列表理解将逐步遍历ID_busca的每个字符，以查看该字符是否在其他两个字符串中

all = [i for i in ID_busca if i in ""YP_207190.2YP_008914846.1"]

---

学会一次编写少量代码。在你知道你有要搜索的ID列表之前，不要尝试搜索你的ID。使用print语句。不要再写代码了，除非你写的所有东西都经过了测试并且按你的意愿工作。您发布的代码至少有四个错误

如果你想要一个ID号列表，那么就制作一个ID号列表：搜索关于列表和append和extend方法的在线教程。同时查找sets；我想最简单的方法就是做三组身份证号码，然后简单地取它们的交叉点
