python - 为什么我的程序没有检测到单词 "Address:"或 "Professional:"？

Question

我正在尝试在此配置中搜索纯文本:

Named H Man, MBA
Personal: 
Address: 
Professional: 
0000 Something St 
Apt 000 
City, ST 12345-6789 
No Business Contact Information. 
Academic: 
2019 Bachelors, Education - AF s

我的目标是仅检索本文中地址的第一部分，即“0000 Something St”和“Apt 000”部分。由于明文中的某些条目配置不同，这让情况变得复杂，因此我使用更通用的方法:我尝试查找包含单词“Address:”或“Professional:”的行获取开始我想要的文本部分的行，然后找到其后包含逗号作为结尾的任何行。完成此操作后，我将编写代码以从这些行中删除不需要的所有内容。大多数文本都可以与编写的程序一起使用——只有这个没有输出任何内容，我认为这是因为由于某种原因它没有正确检测到“地址:”或“专业:”一词。

到目前为止我编写的代码是这样的，加上随后输出它们的方法，这不可能是问题:

def FindAddress(person):
    global address
    address = "NA"
    addressUncropped = ""
    lineBeforeAddress = 0
    lineAfterAddress = 0
    personLines = person.splitlines()
    wordList = []
    lineIndex = 0
    for line in personLines:  # This sets up the before and after markers to be used later
        wordList = line.split(" ")
        for word in wordList:
            print(word)
            if word == "Address:" or word == "Professional:" and lineBeforeAddress == 0:
                lineBeforeAddress = lineIndex
            if "," in line and lineAfterAddress == 0 and lineIndex >= lineBeforeAddress:
                lineAfterAddress = lineIndex+1
        lineIndex += 1
    for line in personLines[lineBeforeAddress:lineAfterAddress]:  # This uses the before and after markers to get the address
        addressUncropped += line

如果您有任何其他可能有助于完成此任务的不相关建议，我也想听听。谢谢!

问题是第一行这个条件为真:

if "," in line and lineAfterAddress == 0 and lineIndex >= lineBeforeAddress:

第一行Named H Man, MBA中包含一个逗号。 lineAfterAddress 和 lineBEforeAddress 均为零，因此 lineIndex >= lineBeforeAddress 为 true。您需要检查 lineBeforeAddress 是否已设置，因此还需要条件 lineBeforeAddress > 0。

此外，此测试不应该在 for word in wordList 循环中，因为它只是测试整行，而不是单个单词。

最后的循环可以简化为:

addressUncropped = "".join(personLines[lineBeforeAddress:lineAfterAddress])

完整代码:

def FindAddress(person):
    global address
    address = "NA"
    addressUncropped = ""
    lineBeforeAddress = 0
    lineAfterAddress = 0
    personLines = person.splitlines()
    wordList = []
    lineIndex = 0
    for line in personLines:  # This sets up the before and after markers to be used later
        wordList = line.split(" ")
        for word in wordList:
            if (word == "Address:" or word == "Professional:") and lineBeforeAddress == 0:
                lineBeforeAddress = lineIndex
        if "," in line and lineAfterAddress == 0 and lineBeforeAddress > 0 and lineIndex >= lineBeforeAddress:
            lineAfterAddress = lineIndex+1
        lineIndex += 1
    addressUncropped = "".join(personLines[lineBeforeAddress:lineAfterAddress])
    return addressUncropped
