按分隔符拆分字符串的可能情况

# 示例代码
s = "a,,b,c,,"
parts = s.split(',')
filtered_parts = [part for part in parts if part]
print(filtered_parts)  # 输出: ['a', 'b', 'c']

# 示例代码
import re

s = "a.b.c"
delimiter = "."
escaped_delimiter = re.escape(delimiter)
parts = re.split(escaped_delimiter, s)
print(parts)  # 输出: ['a', 'b', 'c']

# 示例代码
import threading

def split_string(s, delimiter):
    return s.split(delimiter)

s = "a,b,c"
delimiter = ","
threads = []
results = []

for _ in range(3):
    thread = threading.Thread(target=lambda s=s, delimiter=delimiter: results.append(split_string(s, delimiter)))
    threads.append(thread)
    thread.start()

for thread in threads:
    thread.join()

print(results)  # 输出: [['a', 'b', 'c'], ['a', 'b', 'c'], ['a', 'b', 'c']]
