text_widget.insert(1.0, "\\") will only display one slash

The title says all. I have the following code, lines 9 and 18 contain said characters. Is there a way without using chr(92)?

def Conversion(self):
     self.t=self.input.Read()   
     self.columns=1    
     for i in range(len(self.t)):
         if self.t[i]==chr(9):
             self.columns+=1
         elif self.t[i]==chr(10):
             break             
     self.c="\begin{tabular} ["       
     self.c+="c"*self.columns
     self.c+="] \n"
     for i in range(len(self.t)):
         #self.c+=str(ord(self.t[i]))
         #self.c+=" "
         if self.t[i]==chr(9):
             self.c+='&'
         elif self.t[i]==chr(10):
             self.c+='\\'
             self.c+="\n"
         else:
             self.c+=self.t[i] 
     self.c+="\end{tabular}"
     self.output.Write(self.c)  
 

Also my .Write method looks like this:

class Output:
 def __init__(self,master,x):
     self.v=Text(master,width=x)
     self.v.pack(side=RIGHT)
     self.v.insert(1.0,"LaTeX code")
 def Write (self,input):
     self.input=input
     if self.v.get(1.0,END)=="":
         self.v.insert(1.0,self.input)
     else:
         self.v.delete(1.0,END)
         self.v.insert(1.0,self.input)
