Unit 5: Nesting Loops in Python

Summary:

In this lab, you add nested loops to a Python program provided. The program should print the outline of the letter E. The letter E is printed using asterisks, three across and five down. This program uses the print("*") to print an asterisk and print(" ") to print a space.

Instructions:

Write the nested loops to control the number of rows and the number of columns that make up the letter E, as shown below:

***

*

In the loop body, use a nested if statement to decide when to print an asterisk and when to print a space. The output statements have been written, but you must decide when and where to use them.

Execute the program. Observe your output.

Assignment:

# LetterE.py - This program prints the letter E with 3 asterisks

# across and 5 asterisks down.

# Input: None

# Output: Prints the letter E.

NUM_ACROSS = 3 # Number of asterisks to print across

NUM_DOWN = 5 # Number of asterisks to print down

# Write a loop to control the number of rows.

# Write a loop to control the number of columns

# Decide when to print an asterisk in every column.

print("*")

# Decide when to print asterisk in column 1.

print("*")

# Decide when to print a space instead of an asterisk.

print(" ")

# Figure out where to place this statement that prints a newline.

print(" ")
