I want to strip a certain word off of a string. I tried doing this.
string= "Germany Income and Capital Tax Treaty"
string = string.lower().strip('germany')
print(string)I expected to get:"income and capital tax treaty"
Instead I get"income and capital tax treat"
What is it that I do not understand. Also lstrip and rstrip would not provide a solution as I am writing this in a function where a complete match with the word would need to get stripped off of 'either' end.
Any help?
If you can comment out code and your program still works, then yes, that code was optional.
.strip() with no arguments (or None as the first argument) removes all whitespace at the start and end, including spaces, tabs, newlines and carriage returns. Leaving it in doesn't do any harm, and allows your program to deal with unexpected extra whitespace inserted into the file.
For example, by using .strip(), the following two lines in a file would lead to the same end result:
foo\tbar \n
foo\tbar\n
I'd say leave it in.
In this case, you might get some differences. Consider a line like:
"foo\tbar "
In this case, if you strip, then you'll get {"foo":"bar"} as the dictionary entry. If you don't strip, you'll get {"foo":"bar "} (note the extra space at the end)
Note that if you use line.split() instead of line.split('\t'), you'll split on every whitespace character and the "striping" will be done during splitting automatically. In other words:
line.strip().split()
is always identical to:
line.split()
but:
line.strip().split(delimiter)
Is not necessarily equivalent to:
line.split(delimiter)
