The purpose of Python' s assignment statement is to associate names with values in your program. / usr/ bin/ python var = 100 if var = = 200: print " 1 - Got a true expression value" print var elif var = = 150: print " 2 - Got a true expression value. That is so when we overwrite foo with a new string ' Python' on line, bar is a copy of foo the value of bar is not affected. Finally, y is assigned the value of 32.

8 in late will support assignment inside of lambda expressions. Python Operators are used to perform operations on values and variables. The elif statement allows you to check multiple expressions for TRUE and execute a block of code as soon as one of the conditions evaluates to TRUE. 4 Writing Structured Programs.
