function - I keep getting syntax error when using def on python -

note: basic game working on practice project syntax error when defining explosions ( near end of code list... new programming yeah... if great stuck because new more appreciated

as @burhankhalid pointed out, missing ) @ end of line 111 (windowsurface.blit(ghostimagetwo,ghost), causing error noticed.

additionally, have numerous syntax errors. define variables in different case use them (startgame being used startgame, forget close several other )s (line 124, etc). list goes on.

python forgiving language, not forgiving. find editor , use it, learn how debug code, , stop being sloppy. unable write code works otherwise.
