# python example of to print tables count = 1 num = 0 choice = 0 while True: # input the number num = int(input("Enter a number: ")) # break if num is 0 if num == 0: break # terminates inner loop # print the table count = 1 while count <= 10: print(num * count) ...
When it is false, the program comes out of the loop and stops repeating the body of the while loop. Let’s see the following example of Python while loop to understand it better. a = 1 while( a<10): print(” loop entered”, a, “times”) a = a+1 print(“loop ends here”) ...
while var == 1 : # This constructs an infinite loop num=raw_input("Enter a number :") print "You entered: ", num print "Good bye!" 1. 2. 3. 4. 5. 6. 7. 8. 执行上述代码时,将生成以下输出- Enter a number :20 You entered: 20 Enter a number :29 You entered: 29 Enter a...
While loop Loops are used to repeatedly execute a block of program statements. The basic loop structure in Python is while loop. Here is the syntax. Syntax: while (expression) : statement_1 statement_2 ... The while loop runs as long as the expression (condition) evaluates to True and...
Examples of iteration in Python are Loops. Python uses the For Loop, While Loop and Nested Loops. Table of Contents For Loops Example of a for loop Another example of a for loop Loop through words Using the python range function Range Function Syntax ...
this case, we will be using another functionrange()(or alternativelyxrange()can also be used).range()function has already been mentioned in the previous sections too. If you can rememberrange()function can return you a list of numbers according to the arguments that you provide. For example...
How While Loop works in Python? After going through the syntax and flow, we will now understand how the flow actually works. Before we enter the while loop, there is a condition check; basically, it is an expression that returns the Boolean result, which means the output of the expression...
The range() function is typically used with a while loop to repeat a block of code for all values within a range. Let’s discuss different scenarios of using the range() function with a while loop in Python. By specifying start, stop, and step parameters, By excluding the start and ste...
Use the if condition to determine when to exit from the while loop, as shown below. Example: Breaking while loop Copy num = 0 while num < 5: num += 1 # num += 1 is same as num = num + 1 print('num = ', num) if num == 3: # condition before exiting a loop break ...
python "while" loop as these missing statements can lead to an infinite loop in python. For example, if you forgot to increment the value of the variable "i" , the condition "i < x" inside "while" will always return "True". It is therefore advisable to construct this loop carefully ...
