Syntax Error invalid syntax for no apparent reason

Question

I ve been trying to get a fix and can t find why the error keeps appearing  Pmin Pmax w fi1 and fi2 have all been assigned finite values     guess Pmin  Pmax-Pmin    1-w  2  fi1  w  2  fi2    When i remove this line from the code  the same error appears at the next line of code  again for no reason I can think of  Edit  Here is the chunk of code I was referring to   def Psat self  T       pop  self getPborder T      boolean int pop 0        P1 pop 1      P2 pop 2      if boolean          Pmin   float min  P1  P2            Pmax   float max  P1  P2            Tr T self typeMolecule Tc         w 0 5  1 scipy tanh  10  5   Tr-0 6            fi1 0 5  1-scipy tanh 8   Tr  0 4 -1            fi2 0 460 scipy sqrt 1- Tr-0 566   2  0 434  2  0 494          guess   Pmin  Pmax-Pmin    1-w  2  fi1  w  2  fi2     error here          solution   scipy optimize newton funcPsat guess  args  T self

I noticed that invalid syntax error for no apparent reason can be caused by using space in:

print(f'{something something}')

Python IDLE seems to jump and highlight a part of the first line for some reason (even if the first line happens to be a comment), which is misleading.

If you are running the program with python  try running it with python3

I encountered a similar problem  with a syntax error that I knew should not be a syntax error   In my case it turned out that a Python 2 interpreter was trying to run Python 3 code  or vice versa  I think that my shell had a PYTHONPATH with a mixture of Python 2 and Python 3

For problems where it seems to be an error on a line you think is correct  you can often remove comment the line where the error appears to be and  if the error moves to the next line  there are two possibilities   Either both lines have a problem or the previous line has a problem which is being carried forward  The most likely case is the second option  even more so if you remove another line and it moves again    For example  the following Python program twisty passages py   xyzzy    1   plugh   7   generates the error     File  twisty passages py   line 2     plugh   7             SyntaxError  invalid syntax   despite the problem clearly being on line 1     In your particular case  that is the problem  The parentheses in the line before your error line is unmatched  as per the following snippet     open parentheses  1  2             3                     v  v             v fi2 0 460 scipy sqrt 1- Tr-0 566   2  0 434  2  0 494                                                   close parentheses             1             2   Depending on what you re trying to achieve  the solution may be as simple as just adding another closing parenthesis at the end  to close off the sqrt function   I can t say for certain since I don t recognise the expression off the top of my head  Hardly surprising if  assuming PSAT is the enzyme  and the use of the typeMolecule identifier  it s to do with molecular biology - I seem to recall failing Biology consistently in my youth  -

You re missing a close paren in this line   fi2 0 460 scipy sqrt 1- Tr-0 566   2  0 434  2  0 494   There are three   and only two     I hope This will help you
