另一种方法是先将字符串转换成浮点数,再将浮点数转换回字符串,这样可以去除末尾的零。 # 去除字符串末尾的零defremove_trailing_zeros(s):returnstr(float(s))# 测试s="12300"result=remove_trailing_zeros(s)print(result)# 输出: "123.0"s="120.4500"result=remove_trailing_zeros(s)print(result)# 输出:...
在这个示例中,remove_trailing_zeros函数使用正则表达式去掉了浮点数后多余的零。 方法四:使用decimal模块 decimal模块提供了对浮点数学运算更高的精确度,可以避免某些浮点类型的问题。你可以使用它来格式化数字。 fromdecimalimportDecimal num=Decimal('3.0000')formatted_num=num.quantize(Decimal('1'))print(formatted_...

我们运行“type(time.time())”,返回的是float类型。返回时间戳方式的函数主要有time(),clock()等。元组(struct_time)方式:struct_time元组共有9个元素,返回struct_time的函数主要有gmtime(),localtime(),strptime()。下面列出这种方式元组中的几个元素:...

三、浮点型(float): 如:3.14、2.88 每个浮点型都具备如下功能: float 四、布尔值(bool): 真或假 1或 0 五、字符串(str): python中的字符串在C语言中体现为是一个字符数组,每次创建字符串时候需要在内存中开辟一块连续的空,并且一旦需要修改字符串的话,就需要再次开辟空间,万恶的+号每出现一次就会在内从中...
