Python-function programming, python-Function Map () function: Two parameters are received: one is a function and the other is a sequence. The map function applies the input function to each element of the sequence at a time, if any input function is returned, the result is returned as a new sequence. returns an empty sequence (a string is also a sequence) Filter

5+3>9-2 Is that 8>7,python is first calculated and then compared Other arithmetic operations are performed before the boolean operator Python supports comparisons such as:aint = 50 while Booleanexpression:#suite 1#else:#suite2When the while loop Boolean expression is false, the Else statement is entered. Note: A while inside of a break out of the loop also skips the Else statement. Exercise 2 1. #-*-co

Python makes the programming language a simple way to use, but the Python programming language is a real programming language, in addition, it provides more related structures and support for large programs than shell. The following describes the practical application of the

The biggest advantage of the Python programming language is that there is an interactive development environment. After all, Python is interpreted and run, which can greatly save time for each compilation. The Python syntax is simple, there are several built-in advanced data structures, such as wordcodes and lists. Pro
