°  The negation operator has the maximum priority 7: !, not This operator switches true (anything except 0) to false (0) and vice versa. You can use '!' or 'not', whichever you prefer. a = 3 b = 0 Print (!a) 0 Print (not b) 1 °  Operators with priority 6: *, /, //, %, <<, >> Here are some examples for the six operators with the second highest priority. Note that the modulo operator '%' requires an integer on the left side. The '//' operator is mainly known to Python programmers, it is a division with truncation of the result's fractional part. The normal division operator '/' rounds the result to the closest integer if the requested result data type is an integer. a = 2 b = 3. Print (a*b) 6 Print (b*a) 6.0000000000e0 Print (a/b) 1 Print (a//b) 0 Print (b/a) 1.5000000000e0 Print (a%b) 2 Print (b%a) Error - unsupported operator The '//' operator is additionally helpful to truncate floating point numbers without rounding: a=1.7 Print (a//1) 1.0 The shift operators '<<' and '>>' do bitwise binary shifts to the left or right, they require an integer on the left side. A left shift corresponds to a multiplication with 2, a right shift to a division by 2. That's why they have the same priority as '*' and '/'. a = 2 b = 3.000 Print (a<<1) 4 Print (a<<b) 16 Print (a>>1) 1 Print (b>>a) Error - unsupported operator °  Operators with priority 5: +, - a = 2 b = 3.000 Print (a+b) 5 Print (b+a) 5.000 °  Operators with priority 4: &, |, ^ These operators do a bitwise 'and', 'or' and 'xor', there must be an integer on the left side. They are rarely if ever needed in Yanaconda. Unlike in the C programming language, their priority is higher than the comparisons, just like in Python. °  Operators with priority 3: >, >=, <=, <, ==, != All comparison operators have the third lowest priority. They return 1 if the comparison is true, 0 otherwise. Note that '!=' stands for 'is not equal to'. a = 2 b = 3.000 Print (a>b) 0 Print (a<b) 1 Print (a==b) 0 Print (a!=b) 1 °  Operators with priority 2: in The 'in' operator determines if a variable is in a list: anglelist='Alpha','Beta','Gamma' angle='Beta' if angle in anglelist Print 'Yes' Yes °  Operators with minimum priority 1: and, or Logical operators are used most of the time in if/else statements to combine the results of comparisons. a = 2 b = 3 if a==1 or b==3 Print "Hello World!" Hello World!
