Built-in functions INT (x, [, base]): converts a value or string to a decimal number. When base has parameters, X must be a string and base-based. Print int ('20140901', 8) #12345 All (): If all functions are not 0, or if the element is

Branch statements1. Conditional statements If-else, basic grammatical forms such as the following. The part of "[]" can be omitted.If boolean-expression {statement1; } [Else if Boolean-expression {statement2;} ] [Else {statement3; }

Process Control Statementsconditional statements: If statement: *if (Conditional Boolean type) {true}*if (Boolean expression) {true}else{false result}* Multiple if Else if () {}else if () {}else* nested IF switch statement:                     

If, if...else ... Statement if (true) { System.out.println ("execute when True"); Else { System.out.println ("execute when false"); }Switch statement switch (a) { case 1: switch System.out.prin

Sometimes we may need to execute the same piece of code multiple times. In general, statements are executed sequentially: The first statement in a function executes first, followed by the second statement, and so on.Programming languages provide a

A. Logical control statement: I. Conditional statement:the condition is judged first, then the different branches are executed according to the result of judgment . 1. If andif-Else: Determine the value of a Boolean expression to

1. Conditional selection: If statement① Single Branchif judgment condition; then condition is true Branch code FI② Dual Branchif judgment condition; Then condition for true Branch code else condition for false Branch code FI③ Multi-Branchif judgment

1. Sequential structure 1.if statements (1) Legend (2) Three formats A: Format 1 B: Format 2 C: Format 3 2.swich statements Legend: Format: "Note" Input can be an enumeration after Byte,short,int,char;jdk5;

I. If statement format: Supports if/elif/else forms, supports nesting1. When command execution succeeds (and exit status is 0), execute Command22. When the judging condition is the test command, the Command2 is executed when the result is trueif

1. Indent: Indentation is the only way Python represents a block of statements;All statements in a block of statements must use the same indentation, representing a contiguous sequence of logical lines;The first line of the source file does not need
