提取电子邮件主题行中单词 "for" 和左括号“(”之间的单词。电子邮件主题行是输入

Question

客户名称在单词 "for" 之后和开始提案编号的左括号“(”之前。我需要提取客户名称以用于在未来的步骤中查找交易。最简单的设置方法是什么？使用 Zapier 提取模式或使用 Python 中的 Zapier 代码？

我试过了，没用。不过看起来很有希望。

input_data

client = 提醒：Leruths 已向您发送公司名称提案 (#642931)

import regex
rgx = regex.compile(r'(?si)(?|{0}(.*?){1}|{1}(.*?)
{0})'.format('for', '('))
s1 = 'client'
for s in [s1]:
m = rgx.findall
for x in m:
print x.strip()

这个我也试过了，没用。

start = mystring.find( 'for' )
end = mystring.find( '(' )
if start != -1 and end != -1:
result = mystring[start+1:end]

我正在寻找要在我的示例中返回的公司名称。

Answer 1

最快的方式：

start = client.find('for')
end = client.find('(')
result = client[start+4:end-1]
print(result)

使用正则表达式：

result = re.search(r' for (.*) [(]', client)
print(result.group(1))

可能有更简洁的方法来执行此操作，但这是另一个没有正则表达式的解决方案

client = "Reminder: Leruths has sent you a proposal for Business Name (#642931)"

cs = client.split(" ")
name = ""
append = False
for word in cs:
    if "for" == word:
        append = True
    elif word.startswith("("):
        append = False
    if append is True and word != "for":
        name += (word + " ")
name = name.strip()
print(name)

另一种方法：

client = "Reminder: Leruths has sent you a proposal for Business Name (#642931)"

cs = client.split(" ")
name = ""
forindex = cs.index("for")

for i in range(forindex+1, len(cs)):
    if cs[i].startswith("("):
        break
    name += cs[i] + " "
name = name.strip()

print(name)
