To calculate the age from a birthdate in Python, use this function: from datetime import date def age(birthdate): today = date.today() age = today.year - birthdate.year - ((today.month, today.day) < (birthdate.month, birthdate.day)) return age For example: print(age(date(2000, ...
A button widget that triggers the calculate_age() function when clicked. label_result ? A label widget that will display the calculated age. We use the pack() method to position these elements within the application's window. 4. Defining the Calculate Age Function The core functionality of...
def my_function(): """Original function docstring""" print("Original Function") print(my_function.__name__) # 输出:"my_function" print(my_function.__doc__) # 输出:"Original function docstring"4.2 类装饰器与方法装饰器4.2.1 类装饰器的定义与使用 类装饰器可以用来装饰整个类,而非单个函数。
# Apply a custom function to a columndef custom_function(x): return x * 2df['new_column'] = df['old_column'].apply(custom_function) 你可以将自定义函数应用于列,这在需要执行复杂转换时尤其有用。 对时间序列数据重新取样 # Resample time seri...

首先,我们导入print_function和argparse模块。通过从__future__库导入print_function,我们可以像在 Python 3.X 中编写打印语句一样编写它们,但仍然在 Python 2.X 中运行它们。这使我们能够使配方与 Python 2.X 和 3.X 兼容。在可能的情况下,我们在本书中的大多数配方中都这样做。
