I was trying to create a program which tells me in a given text if there are 2 adjacent words which are the same and where in the text file does this happen[ line and word number]. So far I have been able to determine which word number but can't seem to figure out which line it happens in. Would anyone be able to give me a hand please? So far, next to the Error/ No Error, I am able to get the word number but if I could just get the line number as well.
for line in [textfile]:
for x, y in enumerate[zip[line.split[], line.split[][1:]]]:

Why don't you simply use enumerate again in the outer loop?
for line_number, line in enumerate[textfile]:
for x, y in enumerate[zip[line.split[], line.split[][1:]]]:
if[x,y]==[y,x]:
print[line_number,x,y,"Error"]
else:
print[line_number,x,y,"No error"]

You could create a counter where you establish an integer and add 1 to the integer every time you iterate over a line. For example:
file_name = "whatever.txt"
textfile = open[file_name, "r"]
line_number = 0 # this integer will store the line number
for line in [textfile]:
line_number += 1
for x, y in enumerate[zip[line.split[], line.split[][1:]]]:
if[x,y]==[y,x]:
print[x,y,"Error"]
else:
print[x,y,"No error"]

Here's a solution that can handle x with single or multiple rows like scipy pdf:

The print[] method in Python automatically prints in the next line each time. The print[] method by default takes the pointer to the next line.
Example
Live Demo
for i in range[5]: print[i]
Output
0 1 2 3 4
Modify print[] method to print on the same line
The print method takes an extra parameter end=” “ to keep the pointer on the same line.
The end parameter can take certain values such as a space or some sign in the double quotes to separate the elements printed in the same line.
Syntax
print[“…..” , end=” “]
Print on same line with space between each element
The end=” “ is used to print in the same line with space after each element. It prints a space after each element in the same line.
Example
Live Demo
for i in range[5]: print[i,end=" "]
Output
0 1 2 3 4
Print on same line without space between elements
The end=”” is used to print on same line without space. Keeping the doube quotes empty merge all the elements together in the same line.
Example
Live Demo
for i in range[5]: print[i,end=""]
Output
01234
Print on same line with some sign between elements
The end=”,” is used to print in the same line with a comma after each element. We can use some other sign such as ‘.’ or ‘;’ inside the end parameter.
Example
Live Demo
for i in range[5]: print[i,end=","] print[i,end="."]
Output
0,1,2,3,4, 0.1.2.3.4.

Generally, people switching from C/C++ to Python wonder how to print two or more variables or statements without going into a new line in python. Since the python print[] function by default ends with a newline. Python has a predefined format if you use print[a_variable] then it will go to the next line automatically.
For example:
Python3
print["geeks"]
print["geeksforgeeks"]
Will result in this:
geeks geeksforgeeks
But sometimes it may happen that we don’t want to go to the next line but want to print on the same line. So what we can do?
For Example:
Input : print["geeks"] print["geeksforgeeks"] Output : geeks geeksforgeeks Input : a = [1, 2, 3, 4] Output : 1 2 3 4
The solution discussed here is totally dependent on the python version you are using.
Print without newline in Python 2.x
python
print["geeks"],
print["geeksforgeeks"]
a = [1, 2, 3, 4]
for i in range[4]:
print[a[i]],
Output:
geeks geeksforgeeks 1 2 3 4
Print without newline in Python 3.x
python3
print["geeks", end =" "]
print["geeksforgeeks"]
a =
[1, 2, 3, 4]
for i in range[4]:
print[a[i], end =" "]
Output:
geeks geeksforgeeks 1 2 3 4
Print without newline in Python 3.x without using for loop
Python3
Output:
1 2 3 4 5 6
How do I print an integer on one line?

How do you print on the same line in Python?
Use a carriage return "\r" to print over the same line Use the syntax print[string, end = "\r"] to make the next stdout line begin at the beginning of the current line.
How do I print numbers in Python without space in one line?
To print without a new line in Python 3 add an extra argument to your print function telling the program that you don't want your next string to be on a new line. Here's an example: print["Hello there!", end = ''] The next print function will be on the same line.
How do you print a string and number in one line in Python?
Printing string and integer [or float] in the same line.
+22. x = 8 print["The number is", x] OR x = 8 print["The number is " + str[x]] ... .
+7. If you're using Python 3.6 you can make use of f strings. ... .
+4. ... .
+2. ... .
you can also do x = 8 print["The number is %s" % x] #or print["The number is {0}".format[str[x]]].
