只是关于如何在String中获得所有列表元素的更多信息

a = ['a', 'b', 'c']
str = "a123" 
list(filter(lambda x:  x in str, a))

这取决于上下文 假设你想检查单个文字(任何单个单词a,e,w，..等)就足够了

original_word ="hackerearcth"
for 'h' in original_word:
      print("YES")

如果你想检查original_word中的任何一个字符: 利用

if any(your_required in yourinput for your_required in original_word ):

如果您想要original_word中的所有输入，请使用所有输入 简单的

original_word = ['h', 'a', 'c', 'k', 'e', 'r', 'e', 'a', 'r', 't', 'h']
yourinput = str(input()).lower()
if all(requested_word in yourinput for requested_word in original_word):
    print("yes")

python文档中推荐的regex模块支持这一点

words = {'he', 'or', 'low'}
p = regex.compile(r"\L<name>", name=words)
m = p.findall('helloworld')
print(m)

输出:

['he', 'low', 'or']

实现的一些细节:link

一个惊人的快速方法是使用set:

a = ['a', 'b', 'c']
str = "a123"
if set(a) & set(str):
    print("some of the strings found in str")
else:
    print("no strings found in str")

如果a不包含任何多字符值(在这种情况下使用上面列出的any)，则此方法有效。如果是这样，将a指定为字符串会更简单:a = 'abc'。

你可以使用任何:

a_string = "A string is more than its parts!"
matches = ["more", "wholesome", "milk"]

if any([x in a_string for x in matches]):

类似地，要检查是否找到列表中的所有字符串，请使用all而不是any。

data = "firstName and favoriteFood"
mandatory_fields = ['firstName', 'lastName', 'age']


# for each
for field in mandatory_fields:
    if field not in data:
        print("Error, missing req field {0}".format(field));

# still fine, multiple if statements
if ('firstName' not in data or 
    'lastName' not in data or
    'age' not in data):
    print("Error, missing a req field");

# not very readable, list comprehension
missing_fields = [x for x in mandatory_fields if x not in data]
if (len(missing_fields)>0):
    print("Error, missing fields {0}".format(", ".join(missing_fields)));
