Function - gray1306 - Dec-11-2019
Hello, could someone let me know where am I going wrong with the below code please?
The programs is supposed to ask the user for a number input to make a grid based on that number and an error message if an incorrect number is entered. But at the moment it only generates a 5x5 grid regardless of what is input, if someone could point out my error and help me resolve this that would be greatly appreciate.

# define functions
def GetGridSize():
validGrid = False
while validGrid == False:
print ("Please enter the size of the grid(max 20):")
thisGridsize = int(input())
if (thisGridsize > 0) and (thisGridsize <=20):
validGrid = True
return thisGridsize
def GetGridRow(aRowLength):
# draws a single row using |_ for each square
thisRow = '|_' * (aRowLength)
# add closing | to row
thisRow = thisRow + '|'
return thisRow
def DisplayGrid(aGridSize, aRow):
# display top of grid using _ as top of each square
print(' _' * aGridSize)
# display rows of |_| for each row
for rowCount in range(aGridSize):
print(aRow)
# main program
gridSize = GetGridSize ()
rowToDraw = GetGridRow(5)
DisplayGrid(5, rowToDraw)

That's because lines 29 and 30 have 5's hard coded. Those should be replaced with gridSize.

Thank you so now I have this and have this error - line 31, in <module>
rowToDraw = GetGridRow(Gridsize)
NameError: name 'Gridsize' is not defined
what does it mean? sorry if I sound a bit thick

Python is case sensitive. gridSize != Gridsize.
