python怎么去除空字符串
有几种方法可以去除字符串中的空字符串:
def remove_empty_strings(strings): result = [] for string in strings: if string != "": result.append(string) return result
def remove_empty_strings(strings): return [string for string in strings if string != ""]
def remove_empty_strings(strings): return list(filter(lambda string: string != "", strings))
可以通过调用这些函数来去除字符串中的空字符串,例如:
strings = ["hello", "", "world", "", "python"] result = remove_empty_strings(strings) print(result)
输出:
['hello', 'world', 'Python']
