在上述示例中,我们定义了一个convert_to_float_with_2_decimal_places()函数,该函数接受一个字符串参数s,将其转换为浮点数并保留2位小数。然后,我们使用字符串"3.14159"调用该函数,并将返回值打印出来。 总结 本文介绍了如何在Python中将字符串转换为浮点数并保留2位小数。我们通过使用float()函数将字符串转换为...
You can simply use str method to convert float to String. Let’s understand with the help of simple example. 1 2 3 4 f=1.23444432 print("Converted f to String:",str(f)) Output: Converted f to String: 1.23444432 Let’s say you want to format String to only two decimal places. You ...
FloatProcessor- num: float+round_to_two_decimals() : float+format_to_two_decimals() : str+floor_to_two_decimals() : float 旅行图 让我们用一个旅行图的示例来说明使用上述三种方法处理浮点数的过程: 使用round函数 FloatProcessor->FloatProcessor FloatProcessor->FloatProcessor FloatProcessor-->FloatP...
Method 2: Convert Python Float to a String in Python by Applying the “f-string” Method In Python version “3.6”, the “f-string” method was introduced for formatting strings in Python. The “f-strings” is a string literal that starts with an “f” or “F” and is followed by c...
float可以表示非常大或非常小的数值，并且支持小数点后的精度。在Python中，可以使用两种方式表示float：一种是直接输入带有小数点的数字，另一种是通过科学计数法表示。基本用法 定义float变量：在Python中，可以使用赋值语句定义float变量。例如：a = 3.14 b = 2.71828print(f'type(a) => {type(a)}')print...
💡 Solution 2: Using String formatting ❖ Conclusion ❖ Problem Formulation In this article, you will learn how to format a floating-point value and generate a float number with two decimal places. Example: In the following code, we are calculating the area of a circle. 1 2 3 4 ...
These approaches include round() function, math library, string formatting, format() function, and f-strings. We will use the float data type to illustrate each. Let’s start with the most straightforward method for rounding a number. Use the round() Function to Round to Two Decimal Places...
浮点型(float) 布尔型(bool) 复数性(complex) 字符型(string):表示数据组成是字符 列表(list):用来表示一组有序元素,后期数据可以修改 ['A','B','C'] 元组(tuple):用来表示一组有序元素,后期数据不可修改 ('A','B','C','1') 集合(set):一组数据无序不重复元素 set([1,2,3,4]) 字典(dictio...
# string.startswith(obj, beg=0,end=len(string)) 检查字符串是否是以 obj 开头,是则返回 True,否则返回 False。如果beg 和 end 指定值,则在指定范围内检查. # string.strip([obj]) 在 string 上执行 lstrip()和 rstrip() # string.swapcase() 翻转 string 中的大小写 # string.title() 返回"标题...
