# Python Assignment Operators Example

Advertisements

Assume variable a holds 10 and variable b holds 20, then −

Operator | Description | Example |
---|---|---|

= | Assigns values from right side operands to left side operand | c = a + b assigns value of a + b into c |

+= Add AND | It adds right operand to the left operand and assign the result to left operand | c += a is equivalent to c = c + a |

-= Subtract AND | It subtracts right operand from the left operand and assign the result to left operand | c -= a is equivalent to c = c - a |

*= Multiply AND | It multiplies right operand with the left operand and assign the result to left operand | c *= a is equivalent to c = c * a |

/= Divide AND | It divides left operand with the right operand and assign the result to left operand | c /= a is equivalent to c = c / ac /= a is equivalent to c = c / a |

%= Modulus AND | It takes modulus using two operands and assign the result to left operand | c %= a is equivalent to c = c % a |

**= Exponent AND | Performs exponential (power) calculation on operators and assign value to the left operand | c **= a is equivalent to c = c ** a |

//= Floor Division | It performs floor division on operators and assign value to the left operand | c //= a is equivalent to c = c // a |

### Example

Assume variable a holds 10 and variable b holds 20, then −

#!/usr/bin/python a = 21 b = 10 c = 0 c = a + b print "Line 1 - Value of c is ", c c += a print "Line 2 - Value of c is ", c c *= a print "Line 3 - Value of c is ", c c /= a print "Line 4 - Value of c is ", c c = 2 c %= a print "Line 5 - Value of c is ", c c **= a print "Line 6 - Value of c is ", c c //= a print "Line 7 - Value of c is ", c

When you execute the above program, it produces the following result −

Line 1 - Value of c is 31 Line 2 - Value of c is 52 Line 3 - Value of c is 1092 Line 4 - Value of c is 52 Line 5 - Value of c is 2 Line 6 - Value of c is 2097152 Line 7 - Value of c is 99864
