将字符串与list元素匹配

# 示例列表
my_list = ["apple", "banana", "cherry", "date"]

# 要匹配的字符串
target_string = "banana"

# 精确匹配
matched_elements = [item for item in my_list if item == target_string]

print(matched_elements)  # 输出: ['banana']

# 示例列表
my_list = ["apple", "banana", "cherry", "date"]

# 要匹配的字符串
target_string = "an"

# 部分匹配
matched_elements = [item for item in my_list if target_string in item]

print(matched_elements)  # 输出: ['banana', 'date']

import re

# 示例列表
my_list = ["apple", "banana", "cherry", "date"]

# 要匹配的正则表达式
pattern = r"^a.*e$"

# 正则表达式匹配
matched_elements = [item for item in my_list if re.match(pattern, item)]

print(matched_elements)  # 输出: ['apple']

# 示例列表
my_list = ["apple", "banana", "cherry", "date", "grape"]

# 要匹配的字符串
target_string = "an"

# 部分匹配并去重
matched_elements = list(set([item for item in my_list if target_string in item]))

print(matched_elements)  # 输出: ['banana', 'date']

import re

# 示例列表
my_list = ["apple", "banana", "cherry", "date"]

# 错误的正则表达式
pattern = r"^[a-z]{5}$"  # 这个正则表达式要求字符串长度为5，但列表中没有符合条件的元素

# 正则表达式匹配
matched_elements = [item for item in my_list if re.match(pattern, item)]

print(matched.findall_elements)  # 输出: []
