I'm not able to do it, it seems a little difficult

Answer 1

Below I've put code for producing a square of arbitrary size greater than 1. I've added comments to help clarify what's going on. But first, note in many of the prints, you see end="". That's how you prevent python from printing the next print statement on a new line.

def square(sidelen):

# Error check the input to ensure that it's in bounds.

if (sidelen < 2):

print("Error: Side length of square must be greater than 1!")

# print the top-left "+"

print("+", end="")

# print the dashes across the top. We need sidelen-2 of them, because

# the two "+" account for two of the side's length.

for _ in range(sidelen-2):

print("-", end="")

# print the top-right "+"

print("+")

# this outer for-loop provides sidelen-2 rows between the top and bottom.

for _ in range(sidelen-2):

# for each row, first print the left "|"

print("|", end="")

# print sidelen-2 spaces, as the left and right "|" account for 2 of

# the length

for _ in range(sidelen-2):

print(" ", end="")

# for each row, first print the right "|"

print("|")

# print the bottom-left "+"

print("+", end="")

# print the dashes across the bottom. We need sidelen-2 of them, because

# the two "+" account for two of the side's length.

for _ in range(sidelen-2):

print("-", end="")

# print the bottom-right "+"

print("+")

# this is how you declare a main method in python!
