如何修改Print语句放入循环，适配0°到80°步长10°的角剪切值计算

核心改动点 #

• 调整Shear类的构造方法，支持自定义传入角剪切角度参数，无需修改类内部代码即可切换不同计算参数
• 新增主程序循环逻辑，遍历0°~80°（步长为10°）的所有角剪切取值，逐个实例化计算并打印对应结果
• 可选优化__repr__输出格式，增加字段间隔、保留4位小数提升可读性，可根据需求自行调整精度

完整可运行代码 #

import numpy as np

## 角剪切计算类
class Shear(object):
    # 构造方法支持自定义传入角剪切角度，默认值保留原逻辑的10°
    def __init__(self, angularShear=10):
        self.angularShear = angularShear

    # 自定义打印输出格式
    def __repr__(self):
        return (f'Angular Shear: {self.angularShear:2d}°  '
                f'Shear Strain: {self.shearStrain():.4f}  '
                f'majorAxis: {self.majorAxis():.4f}  '
                f'minorAxis: {self.minorAxis():.4f}')
    
    # 计算剪切应变
    def shearStrain(self):
        return np.tan(self.angularShear * np.pi / 180.)

    # 计算长轴应变
    def majorAxis(self):
        sigma = self.shearStrain() / 2.
        return ((sigma**2 + 1.0)**0.5) + sigma

    # 计算短轴应变
    def minorAxis(self):
        sigma = self.shearStrain() / 2.
        return ((sigma**2 + 1.0)**0.5) - sigma

if __name__ == '__main__':
    # 遍历0°到80°，步长10°
    for angle in range(0, 81, 10):
        shear_calculator = Shear(angularShear=angle)
        print(shear_calculator)
