变量未作为Arg[python]传递

Question

我试图根据接收到的输入自动执行函数，但当我尝试将输入作为和arg传递给函数时，出现了一个错误。这是我想做的一个例子

var ='hello world'

def example(data):
    #function code

example(var)

这是我所做的事情的一个基本用法，它返回一个错误，比如

var is not defined

这是我的实际代码

                    elif city2 != 0:

        elif datasearch[i] in nlp:
            data = datasearch[i]
            datacom = typeremoval(functiongrep(AriaNLP))

#dataProcess('Aria how far am I from Arizona')
def functiongrep(function):
    string = ''
    functions_list = [o for o in getmembers(function) if isfunction(o[1])]
    flen = len(functions_list)
    for i in range(flen):
        head, sep, tail = str(functions_list[i]).partition('<')
        string = string + head
    return string

def typeremoval(function):
    func = str(function)
    func = str(''.join(func))

    func = re.sub("[',()]", '', func)
    return func


dataProcess('locate Scottsdale Arizona USA')

我希望dataProcess（）根据给定的输入激活不同的命令

Exception has occurred: NameError
name 'Scottsdale' is not defined
File "/Users/timyc1/Desktop/DeadIdeas/smartroom/Seavernet/Aria/AriaProcessingModule.py", line 58, in dataProcess
eval('AriaLocation.' + activefunction +'(' + city + ',' + state + ',' + country + ')')
  File "/Users/timyc1/Desktop/DeadIdeas/smartroom/Seavernet/Aria/AriaProcessingModule.py", line 95, in <module>
dataProcess('locate Scottsdale Arizona USA')

Answer 1

不要为此使用evaleval几乎从来都不是解决方案

if state != 0:
    getattr(AriaLocation, activefunction)(city, state, country)
elif city2 != 0:
    getattr(AriaLocation, activefunction)(city, cit2)
else:
    print('uh-oh something went wrong')
