Line 5 - a is greater than b
Line 6 - a is either less than or equal to b
Line 7 - b is either greater than or equal to b
Python Assignment Operators:
Assume variable a holds 10 and variable b holds 20, then:
Operator Description Example
=
+=
-=
Simple assignment operator, Assigns values from right side operands to left
side operand
Add AND assignment operator, It adds right operand to the left operand and
assigns the result to left operand
Subtract AND assignment operator, It subtracts right operand from the left
operand and assigns the result to left operand
c = a + b will assign
value of a + b into c
c += a is equivalent to
c = c + a
c -= a is equivalent to
c = c - a
*=
Multiply AND assignment operator, It multiplies right operand with the left
operand and assigns the result to left operand
c *= a is equivalent to
c = c * a
/=
Divide AND assignment operator, It divides left operand with the right
operand and assigns the result to left operand
c /= a is equivalent to
c = c / a
%=
Modulus AND assignment operator, It takes modulus using two operands
and assigns the result to left operand
c %= a is equivalent
to c = c % a
**=
Exponent AND assignment operator, Performs exponential (power)
calculation on operators and assigns value to the left operand
c **= a is equivalent
to c = c ** a
//=
Floor Dividion and assigns a value, Performs floor division on operators and
assigns value to the left operand
c //= a is equivalent to
c = c // a
Example:
Try following example to understand all the assignment operators available in Python programming language:
#!/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
