rounded_num = round(num) print("Rounded number:", rounded_num) 在这个示例中,将浮点数 10.8 四舍五入为最接近的整数。 四舍五入为指定精度的小数 num = 10.876 rounded_num = round(num, 2) print("Rounded number with 2 decimal places:", rounded_num) 在这个示例中,将浮点数 10.876 四舍五入...
print() Sample Output:Original Number: 3.1415926 Formatted Number with sign: +3.14 Original Number: -12.9999 Formatted Number with sign: -13.00 Flowchart:Python Code Editor:Previous: Write a Python program to print the following floating numbers upto 2 decimal places. Next: Write a Python program ...
decimal_places = 2:设置希望保留的小数位数为2位。 for row in matrix:遍历矩阵的每一行。 formatted_row = [format_number(num, decimal_places) for num in row]:对每个数字调用format_number函数进行格式化。 print(" ".join(formatted_row)):将格式化后的数字组合并打印。 第四步:调试和测试代码 在实际...
1.1 数值型(number) 例子: a, b, c, d = 20, 5.5, True, 4+3j print(a, b, c, d) # 20 5.5 True (4+3j) print(type(a), type(b), type(c), type(d)) # <class 'int'> <class 'float'> <class 'bool'> <class 'complex'> Python也可以这样赋值: ...
>>> 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....

2. Using the format() Function 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...
Being callable means that you can call the object with a pair of parentheses and appropriate arguments, as you’d call any Python function.The number variable isn’t callable, and the function returns False, accordingly. In contrast, the print() function is callable, so callable() returns ...
