I was trying to print out the records of customer in list using for loop, but every item in the list was printed out in every new line. Therefore, I tried to use end="" to print every item on the same line, but how can I print another customer records on next line whenever the the last column of records is printed out?
customer_list = [["ctm1","jaconsdsdsd","ja@gmail.com","+60123954213","15/5/1990"],["ctm2","jactin","jac@gmail.com","+60123237213","15/5/1990"],["ctm3","jactmartin","jacksontai@gmail.com","+60166191111","15/5/1990"]]
# show records of customer account info
def view_customer_account():
# initialize column length
column_length = [2,8,13,12,13]
# loop for longest data length and make it as column length
# column length will remain as initial column length if longest data length is shorter than it
for customer in customer_list:
for i in range(len(column_length)):
if len(customer[i]) > column_length[i]:
column_length[i] = len(customer[i])
# print column name
# column name string will concatenate with a space which multiply with (column length - initial column length)
print(f'| ID{" "*(column_length[0]-2)} | Username{" "*(column_length[1]-8)} | Email Address{" "*(column_length[2]-13)} | Phone number | Date of Birth |')
# print records
# records(str) will concatenate with a space which multiply with (column length/initial column length) - records str length
for customer in customer_list:
for i in range(len(column_length)):
print(f'| {customer[i]+" "*(column_length[i]-len(customer[i]))} ',end="")
view_customer_account()
Output without using end="" :
| ID | Username | Email Address | Phone number | Date of Birth |
| ctm1
| jaconsdsdsd
| ja@gmail.com
| +60123954213
| 15/5/1990

| ctm3
| jactmartin

Output with end="" :
| ID | Username | Email Address | Phone number | Date of Birth |
| ctm1 | jaconsdsdsd | ja@gmail.com | +60123954213 | 15/5/1990 | ctm2 | jactin

Expecting output:
| ID | Username | Email Address | Phone number | Date of Birth |
| ctm1 | jaconsdsdsd | ja@gmail.com | +60166197213 | 15/5/1990 |
| ctm2 | jactin | jac@gmail.com | +60166197213 | 15/5/1990 |
| ctm3 | jactmartin | jacksontai@gmail.com | +60166197213 | 15/5/1990 |
Add print('|')
after the inner for
loop to print the last |
character of each row and insert a new line:
for customer in customer_list:
for i in range(len(column_length)):
print(f'| {customer[i] + " " * (column_length[i] - len(customer[i]))} ', end="")
print('|') # add this one
Output:
| ID | Username | Email Address | Phone number | Date of Birth |
| ctm1 | jaconsdsdsd | ja@gmail.com | +60123954213 | 15/5/1990 |
| ctm2 | jactin | jac@gmail.com | +60123237213 | 15/5/1990 |
| ctm3 | jactmartin | jacksontai@gmail.com | +60166191111 | 15/5/1990 |
Just add a print()
statement (without any parameters) in the outer loop. One level left of the "innermost" print
add the end of your code.
It will just advance the "cursor" to a new line without actually printing anything.
