Question

I have made a table where the user could input his/her own values.

Answer 1

The program is to work as shown in the picture.

Answer 2

I was able to make the program. However, my program displays the values in a list, unaligned.

Is there a way I could make the numbers display as a string and perfectly aligned?

I have not learned .join yet. So if there is another way, even if it may be more complicated, please show me.

Answer 3

Answer 4

Using Python. The initial goal is to create a program where the user inputs the number of rows and columns. Then the user would input the values for each row. Then through the given input of values, the program would create a table.

Answer 5

Here is my current code: (If anyone wants to tinker with it)

def main():
rowsList =[]

while True:
try:
row = int(input("Please Enter the Number of Rows: "))
while row < 0 :
print("Invalid Input (No Negative Numbers)")
row = int(input("Please Enter the Number of Rows: "))
except ValueError:
print("Invalid Input")
continue
else:
break

while True:
try:
col = int(input("Please Enter the Number of Columns: "))
while col < 0 :
print("Invalid Input (No Negative Numbers)")
col = int(input("Please Enter the Number of Columns: "))
except ValueError:
print("Invalid Input")
continue
else:
break
print()


for i in range(1,col+1):
print("[Column " + str(i)+ "]")
for x in range (1,row+1):
rowNum = int(input("Enter the Value (Row " + str(x) + "): "))
rowsList.append(int(rowNum))
print()

Table(rowsList,row)

def Table(rowsList,row):
for num in range (0,row):
print(str(rowsList[int(str(num)):len(rowsList):row]))
main()

Answer 6

you can have list of lists so

Answer 7

for example, this is like having 3 rows
A=[ [ ],[ ],[ ] ]

and 3 colums and 3 rows is this
A=[ [0,0,0],[0,0,0],[0,0,0]]

Answer 8

Yea but the User would have to specify how many rows and columns there will be. So I can't make a fixed list.

Answer 9

Is there a way I could make my code display that outcome as a string instead of a list?

Answer 10

without using .join, I haven't learned that yet.

Answer 11

okay here is a way to initialize a set of row and col

Answer 12

?

Answer 13

R=3
C=3
A=[]
for i in range(R):
A.append([])
for j in range(C)
A[i].append(0)

Answer 14

u can make R and C userinput

Answer 15

R=int(input('Rows:= '))
C=int(input('col:= '))
A=[]
for i in range(R):
A.append([])
for j in range(C)
A[i].append(0)

Answer 16

then for gathering data

Answer 17

R=int(input('Rows:= '))
C=int(input('col:= '))
A=[]
for i in range(R):
A.append([])
for j in range(C):
A[i].append(int(input('enter value of ' + str(i+1)+',' + str(j+1)+' :')))
print A

Answer 18

Hm I've never seen it like that before
Where you have the name of your list than an index before the append.

Answer 19

it means to append it to that part of the list index

Answer 20

uve learnt about indexing through lists right

Answer 21

do they want u to print in table form btw

Answer 22

R=int(input('Rows:= '))
C=int(input('col:= '))
A=[]
for i in range(R):
A.append([])
for j in range(C):
A[i].append(int(input('enter value of ' + str(i+1)+',' + str(j+1)+' :')))
for i in range(R):
print A[i]

Answer 23

use that if u want to printe in table form or the other one if u just want A displayed

Answer 24

Yea I have, i just never seen it before append before like that. lol

Answer 25

welll i dunno what to say, its normal

Answer 26

do u understand wat its doing

Answer 27

I mean its doing pretty much the same thing that my code was doing. It is displaying the table like a list. But yours isnt displaying the given numbers vertically as shown in the picture for the table.

Answer 28

what do u mean its not vertical

Answer 29

Gimme a sec

Answer 30

okay i see ur code its looks fine,

Answer 31

what do u want the print to look like

Answer 32

a bit confused rn

Answer 33

Sorry. Gimme a sec.

Answer 34

okay

Answer 35

Like this other lab prints a multiplication table.
Its doesnt have the brackets and commas and is perfectly aligned.

I wanted it to be like that.

Answer 36

u can join each value of a list to another value with a bunch of spaces inbetween and print

Answer 37

using .join?
I haven't learned that yet. So i don't think my professor would approve of it.

Answer 38

no dont use join

Answer 39

R=int(input('Rows:= '))
C=int(input('col:= '))
A=[]
for i in range(R):
A.append([])
for j in range(C):
A[i].append(int(input('enter value of ' + str(i+1)+',' + str(j+1)+' :')))
for i in range(R):
print A[i]

for i in range(len(A)):
row=''
for j in range(len(A[i])):
row = row + str(A[i][j]) +' '
print row

Answer 40

hey u there?

Answer 41

oh actually i dont think that allings it nicely if u got bigger numbers right

Answer 42

u can use a formula for allignment

Answer 43

like so
R=int(input('Rows:= '))
C=int(input('col:= '))
A=[]
for i in range(R):
A.append([])
for j in range(C):
A[i].append(int(input('enter value of ' + str(i+1)+',' + str(j+1)+' :')))
for i in range(R):
print A[i]

for i in range(len(A)):
row=''
for j in range(len(A[i])):
row = row + str(A[i][j]) +(10-len(str(A[i][j])))*' '
print row

Answer 44

r u there?! u always leave -.-

Answer 45

you can even make this like a robust table, by account for max string length

Answer 46

accounting

Answer 47

for example u can use maxstring length variable instead 10, so just like add 3 spaces or something extra to max string length

Answer 48

Sorry Sorry, was occupied by stuff.

Answer 49

row = row + str(A[i][j]) +(10-len(str(A[i][j])))*' '

What does that do?
That looks super confusing xD

Answer 50

Space it out so that it's more readable. It pads str( A[ i ][ j ] ) with spaces to be 10 characters long. It's a good piece of code to understand and play with. It's also a lesson in commenting nifty bits of code.
