'How to remove a space/whitespace from a string while concatenate operation in Python

I have this:

print('abcd'+'_',cariable)

which gives me this:

abcd_ 2021_mc.txt

But i need this : abcd_2021_mc.txt i.e. no space between _ and 2.

Can anybody suggest me on this. it would be of a great HELP !! thanks in Advance :)

Solution 1:^[1]

If the variable cariable is a string then you can do string concatenation directly and just do print('abcd'+'_'+cariable). That should result in abcd_2021_mc.txt.

Solution 2:^[2]

You can control the separator used by print using the sep parameter.

>>> print('abcd','2021_mc.txt', sep='')
abcd2021_mc.txt
>>>

Solution 3:^[3]

You can build string using the + operator:

a = '_' + '2021'

Solution 4:^[4]

This gives you what you want:

print('abcd' + '_' + cariable)

Solution 5:^[5]

You can use sep argument for print function.

print("abcd", cariable, sep='_')

Solution 6:^[6]

I am not sure why you are concatenating 'abcd' and '_' when the results are clearly 'abcd_'.

When you print multiple fields, the default separator is a space. But you can override that. I can only deduce that cariable is '2021_mc.txt', so:

print('abcd', '_', cariable, sep='') # no space between 'abcd', '_', and cariable
#or:
print('abcd_', cariable, sep='')
#or:
print('abcd' + '_', cariable, sep='')

Update

>>> cariable = '2021_mc.txt'
>>> print('abcd', '_', cariable, sep='') # no space between 'abcd', '_', and cariable
abcd_2021_mc.txt
>>> #or:
>>> print('abcd_', cariable, sep='')
abcd_2021_mc.txt
>>> #or:
>>> print('abcd' + '_', cariable, sep='')
abcd_2021_mc.txt
>>>

Solution 7:^[7]

Using f-strings:

print(f"abcd_{cariable}")

If you need to have "abcd" and "_" separated:

s = "abcd"
print(f"{s}_{cariable}")
