I want my output to be free of line breaks?-CodePudding

table = [[False,False,False,False,False], [False,False,True,False,True]]
    
#not changes------------------
for lines in table:
    for item in lines:
        print("%s\t" % item)
    print("\n")
#-----------------------------

I want output is:

False False False False False
False False True False True

But my output is:

False
False
False
False
False

False
False
True
False
True

print() has some extra parameters, the defaults being

print(value, ..., sep=' ', end='\n', file=sys.stdout, flush=False)

Notice the end='\n' - basically whenever you call print(), end is added to the end of whatever you're printing. You'll want to remove this additional \n by doing print(value, end='').

This will get you:

False   False   False   False   False

False   False   True    False   True

which still doesn't seem to be what you want. Replacing the \t with gets you a bit closer:

False False False False False 

False False True False True

And finally, since you know \n is added to the end of print() by default, you can probably see why print('\n') will actually become print('\n\n') - if you replace your print('\n') with print(), you'll get your desired output:

False False False False False 
False False True False True

Option one:

table = [[False,False,False,False,False], [False,False,True,False,True]]
for lines in table:
    print(str(lines).replace('[', '').replace(']', ''))

Option two:

table = [[False,False,False,False,False], [False,False,True,False,True]]
for lines in table:
    print(','.join([str(item) for item in lines]))

Output:

False, False, False, False, False
False, False, True, False, True

If you want to remove the brackets too, you need to nest one more loop which will unpack the elements of the most inner list and then add a new line for each inner list , as shown in the below code:

table = [[[False,False,False,False,False], [False,False,True,False,True]]
        ,[[False,False,False,False,False], [False,False,True,True,False,True,True]]]
    
#not changes------------------
for lines in table:
    for item in lines:
        for i in item:
            print("%s " % i, end='')# use '\t' if you need more space in between in print("%s\t" % i, end='')
        print()
#         print("%s\t" % item)... commenting this as not in use
    print()
#-----------------------------

Below is the output :

False False False False False 
False False True False True 

False False False False False 
False False True True False True True

Do let me know if this is what you wanted to do or not.

You should probably leverage a pandas here:

table = [[False,False,False,False,False], [False,False,True,False,True]]
import pandas as pd
df = pd.DataFrame(table)
for index, row in df.iterrows():
        row.to_string(index=False).replace('\n', ' ')

output:

'False False False False False'
'False False  True False  True'
