Add leading zeros to a number using format() # Add leading zeros to a number in Python To add leading zeros to a number: Use the str() class to convert the number to a string. Use the str.zfill() method to add leading zeros to the string. The method takes the width of the strin...
The reason Python includes up to the (stop - 1) index is the same reason arange() does not include the stop value, so that the length of the resulting array is equal to stop - start. Next, try changing the step of the slice: Python In [6]: arr_2[1::2] Out[6]: array([2...
