f"{num:.{decimal_places}f}":使用 f-string 格式化字符串,控制输出的小数位数。 第三步:逐行打印矩阵,调用格式化函数 现在我们将遍历矩阵并逐行打印数字,调用上面定义的格式化函数。 decimal_places=2# 设置保留的小数位数print("\n格式化后的矩阵:")forrowinmatrix:formatted_row=[format_number(num,decimal_plac...
NumberFormatter+format(float number, str format)+formatAsPercentage(float number, int decimalPlaces)DecimalFormatter+formatToDecimal(float number, int decimalPlaces)PercentageFormatter+formatToPercentage(float number, int decimalPlaces) 在这个类图中,NumberFormatter作为主要的格式化类,它可以调用DecimalFormatter和...
Theformat()function is another versatile way to format numbers with commas and two decimal places: number = 1234567.8910 formatted_number = "{:,.2f}".format(number) print(formatted_number) Similar to f-strings, the format specifier:,adds commas, and.2fensures two decimal places. The output w...
Create integers and floating-point numbers Round numbers to a given number of decimal places Format and display numbers in stringsLet’s get started!Note: This tutorial is adapted from the chapter “Numbers and Math” in Python Basics: A Practical Introduction to Python 3. If you’d prefer a...
>>> num = 4.123956>>> f"num rounded to 2 decimal places = {num:.2f}"'num rounded to 2 decimal places = 4.12'如果不做任何指定，那么浮点数用最大精度 >>> print(f'{num}')4.123956 格式化百分比数 >>> total = 87>>> true_pos = 34>>> perc = true_pos / total>>> perc0....
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...
Learn how to round a number to 2 decimal places in Python for improved precision using techniques like round(), format(), and string formatting techniques.
number = 0.9124325345 # 百分比 fstring = f'Percentage format for number with two decimal places: {number:.2%}' print(fstring) # Percentage format for number with two decimal places: 91.24% # 保留小数点后3位 fstring = f'Fixed point format for number with three decimal places: {number:.3f...
