python/pyfits syntax errors -

I am currently working on some projects using PyFITS. As a beginner with dragon 3.3, I can not understand the two errors ... 1 error ------------------------

  imported pyphis; \ Hdulist = pyfits.open ('/ user / geographical / desktop / test / case.faces') \ i in category (1,26): \ str = hdulist [0] .header [i]; \ Print (str); \ I = i ++; File "& lt; ipython-input-41-651183e88e23" gt; Category (1,26) in Category I: \ ^ SyntaxError: Invalid syntax   
 Since I look strange "for" and "before the HDUDULIS = ..." ", Like 3 different inputs in the console instead of 1, I can not find any error ...  
 Second Error ------- ----------- ----- I try to handle the index error when I get the HDUlevast [0] .reader [I] = none. In my case it is true for i = 26 or more, so I use it except:  
  try: \ hdulist [0] .header [30] == None: only : \ Print ("end of header") file "ipython-input-28-fe19468a3999", except for row 3: \ ^ SyntaxError: invalid syntax   
 I do not know How will this solve, so if you have any ideas and is enough to help you, thanks! ^^   
 
 
 OK, your syntax is incorrect:  
 
 Indentation cases  
 With the indentation of each line at the end of the disturbance and eliminating your statements, the backslash needs to go away from them.  
 ; Do not end the statement with , this is Python, no. Statement ends with a new line (which, then, avoids your backslash).   
 Then,  
  i = i ++;   
  There is not much understanding in any  language, but in Python there is no  ++  operator and Python to end a statement Do not require a semicolon / for use  
 You want  
  i + = 1   
 In addition,  str  Use this as a way to hide the built-in type in this way.  
 In addition to this, you should never leave a blank :  - Always catch specific exceptions.  
 Finally, do not you really want to compare  any ? If so, then use  
  hdulist [0] .header [30] None # None is a singleton!   
 But everything looks like you should read the original before moving any further.
