To append a string in Python, you can concatenate two separate strings using the + operator, or use the += operator to update a string in place.
Here’s an example of using the + operator:
s1 = "Hello, "
s2 = "world!"
result = s1 + s2
print(result)
Output:
Hello, world!
Here’s an example of using the += operator:
s1 = "Hello, "
s2 = "world!"
s1 += s2
print(s1)
Output:
Hello, world!
Note that strings are immutable in Python, so when you use the + or += operator, the original strings are not modified - a new string containing the concatenated text is created.
There are also other methods for appending strings in Python, such as using the "".join() method with a list of strings or using string formatting methods like f-strings. However, the + and += operators are the most commonly used methods for concatenating strings.
