Python String rstrip() method Example:

Below are the different examples of the Python String rstrip() method.

• Removing trailing spaces from a string by using rstrip() method.
• Removing specific characters from the right side of a string by using rstrip() String method.
• Combining rstrip() with reassignment to modify the original string.
• Using rstrip() to remove trailing tabs from a string.
• Chaining multiple String methods including rstrip().
• By using rstrip() with a string containing various whitespace characters.

Removing trailing spaces from a Python String

text = "   Hello, World!   "
new_text = text.rstrip()
print(new_text)

Run Code >>

Output:

"   Hello, World!"

In this example, the rstrip() method removes the trailing spaces from the text string. The result new_text is a new string with the modified content, leaving the original text unchanged.

Removing specific characters from the right side of a String

text = "ABC123$$$"
new_text = text.rstrip("$")
print(new_text)

Run Code >>

Output:

"ABC123"

Combining rstrip() with reassignment to modify the original string

text = "   Trim me!    "
text = text.rstrip()
print(text)  

Run Code >>

Output:

"   Trim me!"

By using rstrip() to remove trailing tabs from a Python String

code = "\tif x > 10:\t\t\t"
clean_code = code.rstrip("\t")
print(clean_code)

Run Code >>

Output:

"\tif x > 10:"

Only the trailing tabs were removed because the "\t" argument was passed to rstrip().

Chaining multiple String methods including rstrip()

data = "   42 apples   \n"
cleaned_data = data.strip().upper().rstrip("S")
print(cleaned_data)  

Run Code >>

Output:

"42 APPLE"

By using rstrip() with a string containing various whitespace characters

content = "This is a sentence.\n\t  "
trimmed_content = content.rstrip("\n\t ")
print(trimmed_content) 

Run Code >>

Output:

"This is a sentence."

The rstrip() method returns a new string with the specified modifications while leaving the original string unchanged. If you want to update the original string, you need to reassign the result back to the original variable.
