ect answerWhat will be the output of the following Python expression?z = 54.19print("%5.2f"%z)

The output of the Python expression will be "54.19".

Here's the step by step explanation:

1. The variable z is assigned the value 54.19.

2. The print function is used to output the value of z.

3. Inside the print function, a string formatting operation is performed using the % operator. The %5.2f is a placeholder for a float number.

   • The 5 in %5.2f specifies the minimum width of the field. This is the total number of digits and points to be printed. If the number of digits and points in the number is less than 5, spaces will be added at the start.

   • The .2 in %5.2f specifies the number of digits to be printed after the decimal point.

4. Since z is 54.19, which has 5 characters including the decimal point, it fits the width specified and is printed as is.

5. Therefore, the output of the Python expression will be 54.19.
