Error TypeError: String_Editting() takes no arguments

I run this code in Python, but I don’t know why I got the error Type Error: String_Editing() takes no arguments. Can anyone help me?
class String_Editting():
def int(self,total_str,old_substr,new_sunstr):
self.total_str_=total_str
self.old_sunstr_=old_sunstr
self.new_substr_=new_sunstr
self.new_str=total_str
result=self.find()
if result==false:
print(‘your substr is not is total str’)
else:
self.new_str=self.replace(result[0],result[1])

def find(self):
    i=0
    j=0

    start=0
    end=0
    while i<len(self.total_str_):
        if self.total_str_[i]==self.old_sunstr_[j]:
            i+=1
            if j==0:
                start=i
            if j==len(self.old_sunstr_):
                end=i
                return star,end
            j+=1
        else:
            i+=1
            j+=0

    return false

def replace(self,start,end):
    return self.total_str_[:start]+self.new_substr_+self.total_str_[end+1:]

def get(self):
    return self.new_str

obj=String_Editting(‘I am mahsa’,‘mahsa’,‘hesami’)
print(obj.get())

You misspelled the __init__ method as __int__.

Please put all the code between the triple backticks.
