Today, I learned Python, but I had a problem at the beginning. The code was perfectly fine, but every time I ran it, it showed “SyntaxError: Invalid Syntax”.

“SyntaxError: invalid syntax” means “mark> syntax error ;
after query solved the problem, so concluded a solution to this question:

version problem:
because python2 and python3 are incompatible, so some can run on python2 code can not run on python3; You can try to change versions; path problem:
remember to take a closer look at your own path is correct; careless problem: br> f>t to add colon (:) at the end of if, elif, else, for, while, class,def declarations;
used = instead of ==; When installing third-party modules :
when installing third-party modules is also likely to be “SyntaxError: invalid syntax” this problem, then need to check some is installed under the CMD window, at the same time, to the python installation directory, find PIP installation directory inside;
