Pi to two decimal places: 3.14 在这个例子中,{:.2f} 指定了浮点数应该保留两位小数。 从Python 3.6开始,还引入了格式化字符串字面量(也称为f-strings),它们提供了一种更简洁的方式来格式化字符串: python name = "Alice" age = 30 formatted_string = f"Name: {name}, Age: {age}" print(formatted...
(可选) ### 示例 ```python pi = 3.141592653589793 formatted_string = "Pi to two decimal places: {:.2f}".format(pi) print(formatted_string) # 输出: Pi to two decimal places: 3.14 # 数字右对齐,总宽度为10个字符,并用0填充空位 number = 42 formatted_string = "Right aligned number: {:...
例如: - **整数和小数格式化**: ```python pi = 3.1415926 "Pi rounded to two decimal places: {:.2f}".format(pi) # 输出: 'Pi rounded to two decimal places: 3.14' ``` - **填充和对齐**: ```python "Number padded with zeros to length 5: {:05d}".format(42) # 输出: '00042' ...
formatted_pi=f"Pi value rounded to two decimal places is{pi:.2f}"print(formatted_pi) 1. 2. 输出结果与上面相同: Pi value rounded to two decimal places is 3.14 1. 4. 什么时候使用哪个? str.format() 的优点与缺点 优点: 兼容性好,适用于所有 Python 版本。

This is one two three four 带有位置和关键字参数的格式化程序: 当占位符{}为空时,Python将按顺序替换通过str.format()传递的值。 str.format()方法中存在的值本质上是元组数据类型,并且元组中包含的每个单独值都可以通过其索引号(从索引号0开始)进行调用。这些索引号可以传递到花括号中,充当原始字符串中的占位...
Example 9 – Converting Decimal Numbers into Fractions Numbers can be written as mixed fractions, like 11 1/3. The custom codes you can apply for mixed fractions: # #/# –presents a fraction remaining of up to one digit, # ##/## –presents a fraction remaining of up to two digits, ...
()`还支持对字段进行更细致的格式化控制,例如: ```python pi = 3.141592653589793 formatted_string = "Pi to two decimal places: {:.2f}".format(pi) print(formatted_string) # 输出: Pi to two decimal places: 3.14 ``` ### 总结 - **选择f-string**:如果你使用的是Python 3.6或更高版本,并且...
