You can also specify text alignment using the greater than operator:>. For example, the expression{:>3.2f}would align the text three spaces to the right, as well as specify a float number with two decimal places. Conclusion In this article, I included an extensive guide of string data typ...

To round to one decimal place, replace .2 with .1:Python >>> n = 7.126 >>> f"The value of n is {n:.1f}" 'The value of n is 7.1' When you format a number as fixed point, it’s always displayed with the precise number of decimal places that you specify:...
Round to 2 decimal places using the round() function The round() function is Python’s built-in function for rounding float point numbers to the specified number of decimal places. You can specify the number of decimal places to round by providing a value in the second argument. The example...
Template subclasses can specify a custom delimiter. For example, a batch renaming utility for a photo browser may elect to use percent signs for placeholders such as the current date, image sequence number, or file format:>>> >>> import time, os.path >>> photofiles = ['img_1074.jpg'...
Python raises the ZeroDivisionError. However, when you specify a valid numerator and a valid denominator, they’ll be automatically normalized for you as long as they have a common divisor:Python >>> Fraction(9, 12) # GCD(9, 12) = 3 Fraction(3, 4) >>> Fraction(0, 12) # GCD(0,...
decimal_places=2, default=0) order = models.ForeignKey( Order, on_delete=models.CASCADE, related_name='items') 在这里,我们还定义了一个Meta类,以便我们可以为模型设置一些元数据。在这种情况下,我们将verbose_name_plural设置为Order items,以便在 Django 管理界面中正确拼写。然后,我们定义了product_id,na...
