下面是一个完整的示例,将字符串转换为两位小数数字: defconvert_to_two_decimal_places(num_str):num_float=float(num_str)formatted_num="{:.2f}".format(num_float)returnfloat(formatted_num)num_str="3.14159"result=convert_to_two_decimal_places(num_str)print(result)# 输出:3.14 1. 2. 3. 4. 5...
You can use the {:.2f} format formatting to display a number with two decimal places. Update code: import math result = math.floor(1.4) formatted_result = "{:.2f}".format(result) print(formatted_result) #1.00 Share Follow answered Nov 2, 2023 at 14:47 XMehdi01 1 Add a comment...

print("Pi to 2 decimal places is {:.2f}".format(pi)) 输出: Pi to 2 decimal places is 3.14 print("Square root of 2 is {:.2e}".format(math.sqrt(2))) 输出: Square root of 2 is 1.41e+00 print("Binary representation of 10 is {:b}".format(10)) ...
percentage = f"{value:.2f}%" # format the value to a string with 2 decimal places and append a "%" sign print(percentage) # output: 50.00% 在Python中,我们可以使用多种方法来输出百分比。最常用的方法是使用print()函数和格式化字符串。从Python 3.6开始,推荐使用f-strings(格式化字符串字面...
You can use str.format(number) along with .2f inside the placeholder, i.e., {:.2f} . This returns a string representation of the number up to two decimal places, as shown below. Solution: 1 2 3 4 5 6 7 8 import math radius = 5 area = math.pi*radius*radius print("Area = ...
format()函数是Python中常用的字符串格式化方法,可以用来格式化数字。使用方法如下: x = 123.456 print("Formatted number with 2 decimal places: {:.2f}".format(x)) 这里,{:.2f}表示输出浮点数保留2位小数,输出结果为123.46。 更多使用方法: {}:默认的字符串格式化 {:<}:左对齐 {:^}:居中对齐 {:<...
