WebThis creates a situation where x will never be greater than 5, since at the start of the loop code x is given the value of 1, thus, the loop will always end in 2 and the loop will never break. This could be fixed by moving the x = 1 instruction outside the loop. Essentially what this infinite loop does is to instruct a computer to keep on adding 1 to 1 until 5 is reached. WebUse the index number to print a specific record. Look at the table above and remember that Python starts counting at 0 so Edward is record 0, Bella 1 and Jacob 2: To print a specific data value, you need to define the record number and then the data index. When using 2D lists, the first value is the row, and the second value is the column.
