5. 使用 round()函数 使用Python内置四舍五入函数如下所示: number = round(3.14159265, 2) # number is now 3.14 (2 decimal places) 1. 2. 我们可以将数字四舍五入到最接近的10、100、1000等,但传递一个负整数作为第二个参数,示例如下: round(1234567, -1) # 1234570 round(1234567, -2) # 123460...
例如: python name = "Dave" age = 42 print("Name: %s, Age: %d" % (name, age)) print("Pi with two decimal places: %.2f" % pi) 总的来说,Python提供了多种灵活的方式来控制print函数的输出格式,你可以根据具体的需求选择最适合的方法。
print函数就是用来完成这一任务的。而在打印输出的内容时,如何格式化字符串也是开发者必须掌握的技能之一。Python 提供了多种字符串格式化的方法,其中 f-string 格式化自 Python 3.6 版本起成为了最流行的选择之一。 什么是 f-string? f-string,或称格式化字符串字面量,是一种通过在字符串前加上f或F前缀来实现的...
在Python中,print(f) 的用法通常与格式化字符串(也称为 f-strings)相关。f-strings 是从 Python 3.6 开始引入的一种新的字符串格式化方法,它们提供了一种非常简洁和易读的方式来嵌入表达式到字符串常量中。 基本语法 f-string 以字母 f 或F 为前缀,后跟一个字符串字面量。在这个字符串字面量内部,你可以使用...
price=models.DecimalField(max_digits=5,decimal_places=2) #与Publish建立一对多的关系,外键字段建立在多的一方,字段publish如果是外键字段,那么它自动是int类型 publish=models.ForeignKey(to="Publish",to_field="nid",on_delete=models.CASCADE)#foreignkey里面可以加很多的参数,都是需要咱们学习的,慢慢来,to指向...
In this article, we have explored the usage of '0f' in Python's print function. We have learned that '0f' is a formatspecifier used for zero-padding floating-point numbers. By leveraging this option, we can control the precision, decimal places, and add zero-padding to our output. Und...
This requires the use of a semicolon, which is rarely found in Python programs: Python import pdb; pdb.set_trace() While certainly not Pythonic, it stands out as a reminder to remove it after you’re done with debugging. Since Python 3.7, you can also call the built-in breakpoint(...
