python - IDLE idents are 8 spaces instead of 4 - is it a syntax error? -

i new python , have come across weird issue code. know question has been asked before cannot seem find errors in code related other posts.

whenever press [tab], there 8 space indent pose 4 space indent other documents have specified in options. havn't commented code because think problem me having bracket or similar knowing code meant wouldn't make difference. here code:

import os.path import time  def writeline(localfile,lines,currentline):     if lines==(currentline-1):             print("writing document.")             print("the document has been written to.")     else:             writecontent = input("what write line " + str(currentline) + "?\n")             currentline = currentline + 1             write_doc = open(localfile, "a")             if lines==(currentline-1):                     write_doc.write(writecontent)             else:                     write_doc.write(writecontent + "\n")             write_doc.close()             writeline(localfile,lines,currentline)  def writedoc(localfile):     lines = int(input("how many lines document have?\n"))     currentline = 1     time.sleep(0.5)     writeline(localfile,lines,currentline)  def checkdoc(localfile,localmode):     print("verifing file")     time.sleep(0.5)     if localmode!="w":         if os.path.isfile(localfile):             print("the file exists. proceeding.")             time.sleep(0.5)             writedoc(localfile)         else:             print("the file not exist. please either create file or use write function create it.")             time.sleep(0.5)             start()      else:         if os.path.isfile(localfile):             print("the file exists. modify file, please use amend function.")             print("the  file not exist. creating file.")             time.sleep(1)             create_doc = open(localfile, "w")             create_doc.write("")             create_doc.close()             if os.path.isfile(localfile):                 print("file created successfully.")                 writedoc(localfile)         else:             print("the file couldn't created. please ensure that...\n  a) have full admin privileges\n  b) file path correct\n  c) if else fails, try running in elevated session.")  def start():     file = input("please enter full file path of file wish use\n")     time.sleep(0.5)     mode = input("what file, read, write, append or read/write ('r', 'w', 'a' or 'r+')\n")     time.sleep(0.5)     checkdoc(file,mode) start() 

sorry posting whole thing, have no idea error occuring. i'm sure it's simple typo no matter how look, cannot find it. if let me know have gone wrong, great!

i managed find fix, copperfield. went through of code , removed of weird indents , set normal. problem started me accidently pressing [tab] twice! oops!

thanks help! reece coombes
