What will be the output of the following Python expression?N=987print("%06d"%N)Options987000000000987987000000000987

The output of the Python expression will be 000987.

Here's the step by step explanation:

1. The expression "%06d"%N is a string formatting expression in Python.
2. The % operator is used to format a set of variables enclosed in a "tuple" (a fixed size list), together with a format string, which contains normal text together with "argument specifiers", special symbols like %s and %d.
3. %d is used as a placeholder for numeric or decimal values.
4. The number 6 in %06d specifies the length of the output string. If the number of digits in N is less than 6, the output will be filled with zeroes from the left making the total length equal to 6.
5. Therefore, when N=987 is formatted with "%06d", it results in 000987 because three zeroes are added to the left of 987 to make the total length 6.
