Python运行时错误(SyntaxErrorException):必须在此处指定默认值
Python Runtime error (SyntaxErrorException): default value must be specified here
我有以下代码
class PV_gen(object):
def __init__(self,_name,surfacename_,performance_type = "PhotovoltaicPerformance:Simple",performance_name,_integrationmode,No_parallel,No_series):
self.name = _name
self.surfacename = surfacename_
self.performancetype = performance_type
self.performancename = performance_name
self.integrationmode = _integrationmode
self.NOparallel = No_parallel
self.NOseries = No_series
self.PV_performance()
def PV_performance(self,_namenamePVperform = "test",SA_solarcells = 0.5 ,cell_efficiencyinputmode = "Fixed",cell_n = 0.12, schedule_ = "always on"):
self.name = _namenamePVperform
self.surfaceareacells = SA_solarcells
self.cellefficiencyinputmode = cell_efficiencyinputmode
self.efficiency = cell_n
self.schedule = schedule_
每当我尝试在 init 中指定默认值时,我都会收到这样的运行时错误
运行时错误(SyntaxErrorException):必须在此处指定默认值
文件“”,第 5 行
def init(self,name,surfacename,performance_type = "PhotovoltaicPerformance:Simple",performance_name,_integrationmode,No_parallel,No_series):
语法错误:必须在此处指定默认值
我无法弄清楚这里出了什么问题我想指定 performance_type 具有字符串 "PhotovoltaicPerformance:Simple" 的默认值。有人可以给我一些指示吗?
必需的参数必须列在默认参数之前。将具有默认值的参数移动到参数列表的末尾。
你的 default argument
必须 follow non-default argument
。所以参数performance_type
必须在最后声明。
def __init__(self,_name,surfacename_,performance_type = "PhotovoYou ltaicPerformance:Simple",performance_name,_integrationmode,No_parallel,No_series):
应采用以下形式:
def __init__(self,_name,surfacename_,performance_name,_integrationmode,No_parallel,No_series,performance_type = "PhotovoltaicPerformance:Simple"):
类似问题here。
