Control Statements: A control statement is a statement that determines the control flow of a set of instructions. It decides the sequence in which the instructions in a program are to be executed. A control statement can either comprise of one or more instructions. The three fundamental methods of control flow in a programming language are i) Sequential Control Statements ii) Selection Control Statements iii) Iterative Control Statements i) Sequential Control Statements: The code of Python program is executed sequentially from the first line of the program to its last line. That is, the second statement is executed after the first, the third statement is executed after the second, so on and so forth. This method is known as sequential Control flow and these statements called as sequential control statements. ii) Selection Control Statements: Some cases, execute only a set of statements called as selection control statements. This method is known as selection control flow. ...

Features of Python  ● High Level ● Object Oriented ● Scalable: ● Extensible ● Portable ● Easy to Learn ● Easy to Read ● Easy to Maintain ● Robust ● Effective as a Rapid Prototyping Tool ● A Memory Manager ● Interpreted and (Byte-) Compiled Program Output, the print Statement : ● In some languages, such as C, displaying to the screen is accomplished with a function, e.g., printf(), while with Python and most interpreted and scripting languages, it is a statement. ● Many shell script languages use an echo command for program output. print Statement : >>> myString = 'AIMLDS SECSIOT ' >>> print myString SECSIOT >>> myString 'AIMLDS SECSIOT ' The underscore (_) also has special meaning in the interactive interpreter: the last evaluated expression. So after the code above has executed, _ will contain the string: >>> _ SECSIOT ● Python's print statement, paired with the string format operator (%), supports string substitution, much like ...
