Recall the assignment operator. General view can be written in this way
variable = expression
The expression on the right side of the assignment operator allows you to calculate the values of variables using various formulas.
What expression can contain
• integers and real numbers (in real numbers, the integer and fractional parts are separated by a dot, not a comma, as is customary in mathematics)
• signs of arithmetic operations:
+ Addition
- subtraction
* Multiplication
/ Division
** exponentiation
•calls to standard functions (we give only part of a large set. All mathematical functions are described in the math library, which must be connected using the
import math string)
abs(n) module of integer n
math.fabs(x) modulus of a real number x
math.sqrt(x) the square root of the real number x
math.pow(x,y) computes x to the power of y
• parentheses to reorder
When changing the values of variables, it is convenient to use a shorthand notation
| Full string |
Short string |
| a = a + b |
a += b |
| a = a - b |
a -= b |
| a = a * b |
a *= b |
| a = a / b |
a /= b |
