In different programming languages such as C, C++, Java, etc. by default, the printing statements do not end with a newline.
While in the case of Python, we see that the ‘print()’ function by default takes the cursor to the next line after printing the content in it. Let us look at an example where we try to print two different statements.
|
1 2 |
print("Hello, this is Sneh.") print("I love Python") |
Output:
|
1 2 3 |
<span style="color: #008000;"><strong>Hello, this is Sneh. I love Python </strong></span> |
This could be useful while printing the content of each ‘print()’ statement in a newline. But sometimes the user may need to print stuff in the same line.
This could be achieved by using any of the two methods mentioned below for Python 2.0+ or Python 3.0+ users.
Printing with no newlines in Python 3.0+
In Python 3.0+ the ‘print()’ function comes with an additional optional argument ‘end’ which is actually nothing but the terminating string.
Taking the same example as above, but this time using the ‘end’ argument let’s see if we can print both the statements in a single line.
|
1 2 |
print("Hello, this is Sneh.", end="") print("I love Python") |
Output:
|
1 2 |
<span style="color: #008000;"><strong>Hello, this is Sneh.I love Python </strong></span> |
So we can clearly see that just by giving any string into the print function as ‘end’ (as an argument) we can actually separate the print statements with them.
For printing a list without Newline
We can similarly print the contents of a list or an Array without newlines as well. Let’s see how
|
1 2 3 |
list1=['God','is','Good'] for i in range(3): print(list1[i],end=" ") |
Output:
|
1 2 |
<span style="color: #008000;"><strong>God is Good </strong></span> |
Printing with no newlines in Python 2.0+
For Python 2, we can solve the above-mentioned problem by any of the two methods. Firstly if we wan to separate the print statement contents with space( ” ” ) we can use the ‘,’ operator.
Whereas, for other separating string we can use the sys.stdout.write a function from the Sys module in Python 2.
Again, for example, using ‘,’ operator,
|
1 |
print("Hello, this is Sneh again!"), print("I love C++ too.") |
Output:
|
1 2 |
<span style="color: #008000;"><strong>Hello, this is Sneh again! I love C++ too. </strong></span> |
Using sys.stdout.write function in place of ‘print()’,
|
1 2 3 |
import sys sys.stdout.write("Hello, this is Sneh!") sys.stdout.write("I love C++ too.") |
Output:
|
1 2 |
<span style="color: #008000;"><strong>Hello, this is Sneh again!I love C++ too. </strong></span> |
For printing a list without Newline
Using ‘,’ operator
Again looking at an example,
|
1 2 3 |
list1=['Learn', 'Python', 'from', 'JournalDev'] for i in range(4): print(list1[i]), |
Output:
|
1 2 |
<span style="color: #008000;"><strong>Learn Python from JournalDev </strong></span> |
Using the sys module function
Look at this example carefully,
|
1 2 3 4 5 |
import sys list1=['Learn', 'Python', 'form', 'JournalDev'] for i in range(4): sys.stdout.write(list1[i]) sys.stdout.write(",") |
Output:
|
1 2 |
<span style="color: #008000;"><strong>Learn,Python,from,JournalDev </strong></span> |
