TypeError: can only concatenate str (not “float”) to str

Question

I\'m trying to make a program that compares the density of a certain mass and volume to a list of densities of compounds, and return the type of compound I am analyzing.

Answer 1

Use formatted string

str_val = "Hello"
int_val = 1234
msg = f'String and integer concatenation : {str_val} {int_val}'

Output
