Question

def get_name(string, list_names):
    """
    Inputs:
        string: a string to be analyzed
        list_names: a list of names among whom we are looking for
    """
    for name in list_names:
        begin_pattern = re.compile("^\name")
        if begin_pattern.search(string):
            return name

您好我需要搜索字符串中的名称。我的清单是

 list_names = ['LaMarcus Aldridge',
     'Damian Lillard',
     'Wesley Matthews',
     'Arron Afflalo',
     'Robin Lopez',
     'Nicolas Batum',
     'Chris Kaman']

函数不返回任何错误，但它根本不返回任何匹配项。 get_name("Damian Lillard makes 18-foot jumper (Allen Crabbe assists)", list_names)应该让Damian Lillard回归。你能帮助我吗。感谢

Answer 1

编辑：我按照你想要的精神添加代码;忽略我的原始代码。

def get_name(string,list_names):
    for name in list_names:
        if string.startswith(name):
            print(name)


list_names = ['LaMarcus Aldridge',
 'Damian Lillard',
 'Wesley Matthews',
 'Arron Afflalo',
 'Robin Lopez',
 'Nicolas Batum',
 'Chris Kaman']

get_name("Damian Lillard makes 18-foot jumper (Allen Crabbe assists)",   list_names)

返回Damian Lillard。或者，如果你想要LaMarcus Aldridge，而不是改变你的剧本，你可以使用：

get_name("LaMarcus Aldridge makes 18-foot jumper (Allen Crabbe assists)", list_names)

根据你原来的问题，

def get_name(string, list_names):
   for player in list_names:
    if player==string:
        return player


list_names = ['LaMarcus Aldridge',
 'Damian Lillard',
 'Wesley Matthews',
 'Arron Afflalo',
 'Robin Lopez',
 'Nicolas Batum',
 'Chris Kaman']

get_name('Damian Lillard', list_names)

Answer 2

可以使用简单的if x in y，然后检查x中是否存在y。如果字符串包含多个名称，则需要它返回list个名称。可以像这样使用列表理解：

def get_name(string, list_names):
    return [name for name in list_names if name in string]

这是不使用列表理解的相同功能：

def get_name(string, list_names):
    results = []
    for name in list_names:
        if name in string:
            results.append(name)
    return results

Answer 3

试试这个：

import re
def get_name(string, list_names):
    for name in list_names:
        match = re.search(r'\b%s\b'%(name),string)
        if match:
            return name

string ="Damian Lillard makes 18-foot jumper (Allen Crabbe assists)"
list_names = ['LaMarcus Aldridge','Damian Lillard','Wesley Matthews','Arron Afflalo','Robin Lopez','Nicolas Batum','Chris Kaman']

print(get_name(string,list_names))

从python中的名称列表中搜索字符串中的名称
