使用字典理解将字符串解析到字典中的pythonic方法

s = "key1:value1,key2:value2,key3:value3"

# 使用字典理解将字符串解析成字典
dict_from_str = {k: v for k, v in (item.split(':') for item in s.split(','))}

print(dict_from_str)

{'key1': 'value1', 'key2': 'value2', 'key3': 'value3'}

def safe_split(s, delimiter):
    try:
        return s.split(delimiter)
    except ValueError:
        return [s]

s = "key1:value1,key2:value2,key3:value3"

dict_from_str = {}
for item in s.split(','):
    key, value = safe_split(item, ':')
    dict_from_str[key] = value

print(dict_from_str)

import re

def parse_kv_pair(pair):
    match = re.match(r'([^:]+):(.+)', pair)
    if match:
        return match.groups()
    return None, None

s = "key1:value1,key2:value with colon:,key3:value with comma,"

dict_from_str = {k: v for k, v in (parse_kv_pair(item) for item in s.split(',')) if k is not None}
