Structure of Python Program

• A statement is a unit of code that the Python interpreter can execute. We have seen two kinds of statements: print being an expression statement and assignment.
• When you type a statement in interactive mode, the interpreter executes it and displays the result, if there is one.
• A script usually contains a sequence of statements. If there is more than one statement, the results appear one at a time as the statements execute.

Example

print(1)
x = 2
print(x)

Output

1
2
