I had this error  because of a missing closing parenthesis on a line   I started off having an issue with a line saying  invalid syntax   lt string gt   line        at the end of my script   I deleted that line  then got the EOF message

Indent it  first  That would take care of your SyntaxError   Apart from that there are couple of other problems in your program    Use raw input when you want accept string as an input  input takes only Python expressions and it does an eval on them  You are using certain 8bit characters in your script like 0    You might need to define the encoding at the top of your script using   - - coding latin-1 - - line commonly called as coding-cookie  Also  while doing str comparison  normalize the strings and compare   people using lower   it  This helps in giving little flexibility with user input  I also think that reading Python tutorial might helpful to you       Sample Code   - - coding  latin1 - -  while 1      date raw input  Example  March 21   What is the date         if date lower       march 21

Use raw input instead of input        If you use input  then the data you   type is is interpreted as a Python   Expression which means that you   end up with gawd knows what type of   object in your target variable  and a   heck of a wide range of exceptions   that can be generated  So you should   NOT use input unless you re putting   something in for temporary testing  to   be used only by someone who knows a   bit about Python expressions       raw input always returns a string   because  heck  that s what you always   type in     but then you can easily   convert it to the specific type you   want  and catch the specific   exceptions that may occur  Hopefully   with that explanation  it s a   no-brainer to know which you should   use    Reference  Note  this is only for Python 2  For Python 3  raw input   has become plain input   and the Python 2 input   has been removed

While  simon s answer is most helpful in Python 2  raw input is not present in Python 3  I d suggest doing the following to make sure your code works equally well in Python 2 and Python 3   First  pip install future     pip install future   Second  import input from future builtins    my file py     from future builtins import input str value   input  Type something in       And for the specific example listed above     example py from future builtins import input my date   input  Example  March 21   What is the date

After the first if statement instead of typing  if  type  elif  and then it should work   Ex         while 1      date input  Example  March 21   What is the date     if date   June 21       sd  23 5   North Latitude elif date   March 21    date   September 21       sd  0   Latitude  elif date   December 21       sd  23 5   South Latitude  elif sd      print sd

Check if all the parameters of functions are defined before they are called  I faced this problem while practicing Kaggle

I m trying to answer in general  not related to this question  this error generally occurs when you break a syntax in half and forget the other half  Like in my case it was   try           since python was searching for a   except Exception as e          but it encountered an EOF  End Of File   hence the error  See if you can find any incomplete syntax in your code

What you can try is writing your code as normal for python using the normal input command  However the trick is to add at the beginning of you program the command input raw input   Now all you have to do is disable  or enable  depending on if you re running in Python IDLE or Terminal  You do this by simply adding     when needed   Switched off for use in Python IDLE       input raw input    And of course switched on for use in terminal        input raw input    I m not sure if it will always work  but its a possible solution for simple programs or scripts

i came across the same thing and i figured out what is the issue  When we use the method input  the response we should type should be in double quotes  Like in your line date input  Example  March 21   What is the date      You should type when prompted on console  12 12 2015  - note the   thing before and after  This way it will take that as a string and process it as expected  I am not sure if this is limitation of this input method - but it works this way   Hope it helps

Check the version of your Compiler   if you are dealing with Python2 then use -   n  raw input  quot Enter your Input   quot     if you are dealing with python3 use -   n  input  quot Enter your Input   quot
