WebNotice the main difference: in C, the data types of each variable are explicitly declared, while in Python the types are dynamically inferred. This means, for example, that we can assign any kind of data to any variable: # Python code x = 4 x = "four" Here we've switched the contents of x from an integer to a string. WebAccepted answer.
