WebMay 24, 2024 · Solution 1 – Convert Float to Integer. To solve the "TypeError: can't multiply sequence by non-int of type 'float'" error, we can convert the float to an integer. Now we're getting the expected result – the tuple has been duplicated. WebThis was the simplest way of entering an expression for x + 1. We could also enter: >>> y = Symbol('y') >>> x - y + 17 + y - 16 + sin(pi) x + 1. In this case SymPy automatically rewrote the input expression and gave its canonical form, which is x + 1 once again. This is a very important behavior: all expressions are subject to automatic ...
