事实上,字符串对象的 foramt() 方法跟 Python 内置的 foramt() 函数,它们都会调用__format__() 魔术方法,所以,f-string 其实是前文中 format() 格式化写法的升级版。 在默认情况下,format_spec是一个空字符串,而format(value, "")的效果等同于str(value),因此,在不指定其它 format_spec 的情况下,可以简...
Format specifiers in Python control how values appear when formatted, using components like fill, align, sign, width, and type. You align text in Python string formatting using the align component, which can justify text to the left, right, or center within a specified width.When...
print(df.to_string()) 1. 这将输出整个DataFrame。如果我们的数据较大,还可以使用max_rows、max_cols等参数来查看全部内容。 对齐输出 为了让输出看起来更整齐,我们可以通过设置justify参数来实现对齐。对齐方式包括:"left"、"right"和"center"。示例如下: ...
Since Python 3.0, theformatfunction was introduced to provide advance formatting options. print(f'{name} is {age} years old') Python f-strings are available since Python 3.6. The string has thefprefix and uses{}to evaluate variables.
