python conditional assignment

Python conditional statementsConditional statements in Python are implemented in the same way as conditional statements in other languages, either If...else or If...elif...else. They are implemented by one or more execution results (true) or False (false) to determine the code block to execute.The following diagram bri

Conditional judgment statements are a must-have basis for Python programming language learning, and many people feel that they can't remember grammar, and the old boy it education gives you a summary of the relevant language:I. How to use the IF statement(1) Use of If...elseIf...else is a single conditional judgment statement in an IF condition statement, which u

The simplest conditional statement: If expression: expr_true_suite As above, if is a keyword and expression is a conditional expression, conditional expressions support multiple conditional judgments, can be concatenated with Boolean operators and, or, and not, Expr_true_suite is a code block, expression is true,

. TaskUse the while True infinite loop with the break statement to calculate 1 + 2 + 4 + 8 + 16 + ... The first 20 items of the and.Continue continue circulationDuring the loop, you can use break to exit the current loop, and you can use continue to skip the subsequent loop code and continue the next loop. Let's say we've written the code that calculates the average score using the For loop:L = [98, M, M, ba, 85]sum = 0.0n = 0 inL: sum = sum + x n = n + 1print sum/nNow the teacher just wan

Today we look at conditional statements and loop statements.Preview:1. Using while loop output 1 2 3 4 5 6 8 9 102. For all numbers of 1-1003. All odd numbers in output 1-1004. All even numbers in output 1-1005, Beg 1-2+3-4+5 ... 99 of all numbers of the and6. User Login (three chance retry)First, conditional statementsWhen we write a program that requires branching, we can also say that our

1. Conditional Judgment StatementThe keywords for conditional selection statements in Python are: If, elif, else three. Its basic form is as follows:AGE_OF_CC = 27age = Int (Input ("Guessage:")) if Age = = age_of_cc: print ("Yes,you got It!") Elif Age > AGE_OF_CC: print ("Big guess!") else: print ("Guess small!") ")If statement execution is characterized

Getting Started with Python (11) conditional judgment and cyclic condition judgmentComputers can do a lot of automated tasks, because it can make their own conditions to judge.For example, enter the age of the user, print different content according to age, in the Python program, with the if statement implementation:20if age >= 18: print ‘your age is‘, age pri

A python conditional statement is the execution result (true or false) of one or more statements that determines which block of code is executed The Python program language specifies that any non-0 and non-null (NULL) values are true,0 or null to FALSE. Basic situation: If Judge condition 1:EXECUTE statementElif Judgment Condition 2:EXECUTE statementElseEXECUT

First, sequential structureThe sequential structure is the simplest kind of program structure, and the program executes from top to bottom in the order in which the statements are written.Two, branch control statementsA python conditional statement determines the code block that executes by executing the result of one or more statements (true or false).1. If statementThe general form of the IF statement in

Python's judgmentLike other languages, Python also has conditional judgment and looping operations, such as we can write a simple judgment operation: using the IF keyword can be used to achieve the effect of judgment, the following example:1>>> test_if =raw_input ()2503>>>ifTest_if :4...Print "You is so yamg"5...Else:6...Print "You is so old!"7 ... 8 You is so old!9>>>In this simple judgment, first, determi

In this article we have some knowledge of conditional statements, and the Python conditional statement determines the code block that executes by executing the result of one or more statements (true or false). The Python program language specifies any non-0 and non-null (NULL) values of true,0 or NULL to FALSE. pythoni

addition of numbersA = 5= 3= a += 8Arithmetic of subtractionc = A-= 3Arithmetic of multiplicationc = A *= 15The arithmetic of exponentiation in multiplicationD = 2**2= 4Here the * * represents the second party, 2 of the 2-time side. If you want to represent 4 of the 8 parties, you should write 4**8.The operation of divisionA = += 8= A/= 2.375Divisible, Fetchc = A//= 2Take surplusc = a%= 3The remainder is the remaining number after a divided by B, after learning to take the remainder, we can use

Python branching, looping, conditional statement usage I've learned two types of data, 1 are numbers, and 1 are strings. Numbers can be mathematically calculated, and strings can be Text information. Where the number is divided into, integers, floating-point numbers. strings, of course, are strings. integers, floating point numbers are Is the data type that describes the number. And then, to do something

value you entered, if you enter a password like this, do not want to let others see your password, how to do it, you need to use a standard library, Getpass, what is the standard library, is not need you to install, loaded Python on the library, is the standard library, Getpass is a standard library, import in, directly using the Getpass.getpass method can be entered at the time, do not echo, the code is as follows: 123 Import Ge

Computers can do a lot of automated tasks, because it can make their own conditions to judge.For example, enter the age of the user, print different content according to age, in a Python program, with an IF statement:Age = Theif age >=: print('your-is ', age) Print('adult')According to the Python indentation rules, if the IF statement evaluates to True, the indented two lines of the print statement a

A python conditional statement determines the code block that executes by executing the result of one or more statements (true or false). You can easily understand the execution of conditional statements by:The Python program language specifies any non-0 and non-null (NULL) values of true,0 or NULL to FALSE. In

Base: 1. The first sentence of Python usage Python does not limit the suffix name, it can be arbitrary When importing a module, if it is not a. py file (the file suffix later is py) Usage of 2.input: Wait forever until the user enters a value. The input value will be assigned to one thing. 3. Variable Name: -Alphabet -Digital -Underline PS: numbers canno

you terminate from a for or while loop, any corresponding loop else blocks will not execute.The continue statement is used to tell Python to skip the remaining statements in the current loop block and proceed to the next round of loops.A looping statement can have an ELSE clause, which is executed when the exhaustion list (in a For loop) or the condition becomes false (in a while loop), but not when the loop is terminated by a break. The following is
