Removal of the area without a new line

[derk]

My code.

f = open('1.txt', 'r') 
lines = f.readlines()
str1= lines[0]
str2= lines[2]
print(str1,str2)

His conclusion

str number 1
 str number 3

There are lines in 1.txt.

str number 1 
str number 2
str number 3

What I want is out.

str number 1 str number 3

Thank you.

The thing is, the file at the end of each line has a line translation. \nYou need to get rid of it, for example:

str1 = lines[0][:-1]
str2 = lines[2][:-1]
print(str1, str2)

i.e. cut the last symbol (which) \n)

You can do this for the entire file:

lines = [line[:-1] for line in f.readlines()]
