Hmm, I couldn’t find any relevant discussion threads on the iSharkFly forum about Python string splitting. Let me provide a general overview of how to split strings in Python instead:

In Python, you can use the split() method to split a string into a list of substrings. The basic syntax is:

string.split(separator, maxsplit)

Where:

  • separator (optional) is the character used to split the string. If not provided, whitespace is used as the default separator.
  • maxsplit (optional) is the maximum number of splits to perform. If not provided, all occurrences of the separator are used to split the string.

Here are some examples:

my_string = "This is a sample string"
parts = my_string.split()
print(parts)  # Output: ['This', 'is', 'a', 'sample', 'string']

my_string = "apple,banana,cherry"
parts = my_string.split(",")
print(parts)  # Output: ['apple', 'banana', 'cherry']

my_string = "one two three four"
parts = my_string.split(" ", 1)
print(parts)  # Output: ['one', 'two three four']

I hope this general overview of string splitting in Python is helpful! Let me know if you have any other questions.

如何还想是从给定一个字符串中获取子字符串的话，可以采用下面的方法：

my_string="hello python world , i'm a beginner"
print(my_string.split("world",1)[1])
