求问大佬让用户自定义某个值
这波属于赶鸭子上架了{:5_104:} 我需要让用户自己输入他要的值，然后把xml文件中rhop0的值改成他需要的我写的代码是这样的，明显不对,但是我也不知道怎么改{:5_100:}
rhop0_user = input("please input value of rhop0: ")
print(type(rhop0_user))
rhop0_user = int(rhop0_user)
from xml.etree import ElementTree as ET
f = open(r'E:\DualSPHysics_v5.0.5\DualSPHysics_v5.0\examples\inletoutlet\0_inlet+dem\Casein_Def.xml')
xml_text = f.read()
root = ET.fromstring(xml_text)
f.close()
rhop0 = root.find('casedef').find('constantsdef').find('rhop0')
print(rhop0)
root.attrib
rhop0.set('value','rhop0_user')
root.attrib
definition = root.find('casedef').find('geometry').find('definition')
print(definition)
root.attrib
definition.set('dp','0.05')
tree = ET.ElementTree(root)
tree.write("Casein_Def.xml",encoding= 'utf-8')
xml文件部分内容如下:

<hswl value="1" auto="false" comment="Maximum still water level to calculate speedofsound using coefsound" units_comment="metres (m)" />

print(type(rhop0_user))
# rhop0_user = int(rhop0_user) 不要转成整数

root.attrib
