String conversion The operators which we have not already come across will be explained in later chapters. Operators with the same same precedence are listed in the same row in the above table. For example, + and - have the same precedence. Order of Evaluation By default, the operator precedence table decides which operators are evaluated before others. However, if you want to change the orer in which they are evaluated, you can use parentheses. For example, if you want addition to be evaluated before multiplication in an expression, then you can write something like (2 + 3) * 4.

Less Than or Equal To Returns whether x is less x = 3; y = 6; x than or equal to y <= y returns True. >= Greater Than or Equal Returns whether x is x = 4; y = 3; x >= 3 reTo greater than or equal to y turns True. e. e. True). Comparisons can be chained arbitrarily: 3 < 5 < 7 gives True. Compares if the objects x = 2; y = 2; x are equal == y returns True. x = 'str'; y = 'stR'; x == y returns False. x = 'str'; y = 'str'; x == y re20 Operators and Expressions Operator Name Explanation Examples turns True.
