How to Get a Substring of a Python String?
To get a substring of a Python string, you can use the string slicing syntax as follows:
# Define a string
string = "hello world"
# Get the substring "world"
substring = string[6:]
print(substring) # Output: "world"
# Get the substring "lo w"
substring = string[3:7]
print(substring) # Output: "lo w"
In the above example, string is the original string, and substring is the substring that we want to extract. To get a substring, we use the slicing syntax string[start:end], where start is the index of the first character to include in the substring, and end is the index of the first character to exclude from the substring. If start is not specified, it defaults to 0 (the beginning of the string). If end is not specified, it defaults to the end of the string.
