split(): if w == word: count = count + 1 # printing result print("\'%s\' found %d times." %(word, count)) Output'text' found 2 times. 'is' found 1 times. 'Hello' found 0 times. To understand the above program, you should have the basic knowledge of the following Python ...
Your operating system and many of its programs (including the python program on your computer) are probably written in C or C++.These two are harder to learn and maintain. You need to keep track of many details like memory management, which can lead to program crashes and problems that are...
