If you'd like to know more about Python lists, consider checking out DataCamp's 18 Most Common Python List Questions tutorial. Now, there is another interesting difference between a for loop and a while loop. A for loop is faster than a while loop. To understand this you have to look ...
Here, the while loop repeats the code block until the count variable is less than 5. During each iteration, the count variable is incremented by 1, and the current value of the count is printed on a new line as we can see in the output. Nested Loops In Python, a nested loop is a ...
Inside the while loop, the condition to be fulfilled is that the value of‘n’should always be greater than zero. Inside the loop, we add the value of‘n’to‘sum’and then decrement‘n’.While the value of‘n’will become zero, the while loop will stop executing and then print the...
1. Make sure that you use while-loops sparingly. Usually a for-loop is better.尽量节制使用while循环,通常使用for循环会更好些。2. Review your while statements and make sure that the thing you are testing will become False at some point.检查你的while语句,确保它的确会在某些时候是“假”。3....

However, you can use any Python object in a Boolean context, such as a conditional statement or a while loop.In Python, all objects have a specific truth value. So, you can use the logical operators with all types of operands.Python has well-established rules to determine the truth value...
In Python, you can specify an else statement to a for loop or a while loop. The else block is executed if a break statement is not used.
