Hey I wrote a python code (python 2.7.3) with multiple lists, but when I try to print them they always come with a space. I want to print the list in continuous manner but I'm unable to do so. I have one list which have integer values and other with character.
Eg: list1 (integer list has 123) and list2(character list has ABC).
Desired Output: ABC123
What I'm getting: ABC 123
What I did:
print "".join(list2),int("".join(str(x) for x in list1))
Any suggestion what I'm doing wrong?
l = ["A","B","C"]
l2 = [1,2,3]
print "".join(l+map(str,l2))
ABC123
map
casts all ints
to str
, it is the same as doing [str(x) for x in l2]
.
The space comes from the print
statement. It automatically inserts a space between items separated with comma. I suppose you don't need to covert the concatenated string into an integer, then you concatenate strings from join
and print them as one.
print "".join(list2)+"".join(str(x) for x in list1)
Alternatively you can switch to python3's print
function, and use its sep
variable.
from __future__ import print_function
letters=['A','B','C']
nums=[1,2,3]
print("".join(letters),int("".join(str(x) for x in nums)), sep="")
The ,
is what's adding the space since you are printing two things, a string 'ABC' and an integer 123. Try using +
, which directly adds two strings together so you can print the string 'ABC123'
>>> list1=[1,2,3]
>>> list2=['A','B','C']
>>> print "".join(list2),int("".join(str(x) for x in list1))
ABC 123
>>> print "".join(list2)+"".join(str(x) for x in list1)
ABC123
Try concatenating the two lists you want while printing. Use "+" instead of ",". Here 'int' will give error as you can concatenate only strings. So try,
print "".join(list2)"".join(str(x) for x in list1)
print
adds a single space automatically between commas.
You can use the new print function:
from __future__ import print_function
print("".join(list2),int("".join(str(x) for x in list1)), sep="")
See docs .
Note: This function is not normally available as a built-in since the name
print()
function, use this future statement at the top of your module
