So I am trying to make a text-based game of connect-4 for the purposes of better understanding Python and how it actually works.
Short version
Long version
I am trying to use a looping system to print out an array in an evenly spaced and aesthetically pleasing format after every turn is taken, so users have clear feedback of what the current board looks like before the next turn is taken. To do this I want to be able to have lines of code that are as small as possible for making it easier to read the code itself. Although this might not be the best practice for executing this scenario I want to understand this way of coding better so I could apply it to future projects if need be.
In terms of the actual execution, I am trying to use a while loop to append 7 positions of an array one after another in the same output line for array positions that are in the same row. after this, I want to print the next row on the line below the previous one as seen in the code below "Desired output".
Thank you in advance for your answers, suggestions and comments.
Work in progress
import numpy as np
ARRAY = np.zeros(shape=(6, 7), dtype = 'int8')
# In reality I will be using an empty array that gradually gets populated
# Zeros are used for ease of asking the question
def Display_board():
i = 0
while i < 7:
j = 0
print(" ", end = " ")
while j < 8:
print(str(ARRAY[i][j]))
j += 1
i += 1

# It goes on but didn't include as it would take up unnessary space in the question
If I change the line that prints the array to as follows I get another undesired output
print(str(ARRAY[i][j]), end = " ")
#output
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
Current working method - Gives desired output
def Display_board():
for i in range(6):
print(" " + str(ARRAY[i][0]) + " " + str(ARRAY[i][1]) + " " + str(ARRAY[i][2]) \
+ " " + str(ARRAY[i][3]) + " " + str(ARRAY[i][4]) + " " + str(ARRAY[i][5])\
+ " " + str(ARRAY[i][6]))
Desired output
0 0 0 0 0 0 0
0 0 0 0 0 0 0
0 0 0 0 0 0 0
0 0 0 0 0 0 0
0 0 0 0 0 0 0
0 0 0 0 0 0 0
The simple fix is to use end=' ' on the print inside the while loop on j and then add a print() after it:
def Display_board():
i = 0
while i < 6:
j = 0
print(" ", end = " ")
while j < 7:
print(str(ARRAY[i][j]), end=" ")
j += 1
print()
i += 1
Output:
0 0 0 0 0 0 0
0 0 0 0 0 0 0
0 0 0 0 0 0 0
0 0 0 0 0 0 0
0 0 0 0 0 0 0
0 0 0 0 0 0 0
You can also use a nested list comprehension with join to achieve the output in one line:
def Display_board():
print('\n'.join(' '.join([' '] + [str(ARRAY[i][j]) for j in range(7)]) for i in range(6)))
