How to split a string using Python's split() function

How to use Python’s split() function to split a string requires specific code examples

In Python programming, strings are a very common data type. . When processing string operations, sometimes you need to split a string into multiple parts. In this case, you can use the split() function in Python to achieve this.

The split() function is a built-in string method in Python. It can split a string into multiple substrings according to the specified delimiter and store these substrings in a list. Next, we will introduce the use of split() function in detail and give specific code examples.

The basic syntax for using the split() function is as follows:

字符串.split(分隔符, 最大分割次数)

Among them, the string is the original string to be split, and the separator is the mark used to specify the split string. The maximum number of splits refers to the maximum number of substrings that the string can be split into (optional parameter, default is all). When the maximum number of divisions is reached, the remaining string will be added to the returned list as the last element.

Below, let’s look at a few specific code examples:

Example 1: Split a string using spaces

str1 = "Hello World"
result = str1.split()  # 使用空格作为分隔符
print(result)

Output result:

['Hello', 'World']

Example 2: Split a string using commas

str2 = "apple,banana,orange"
result = str2.split(',')  # 使用逗号作为分隔符
print(result)

Output result:

['apple', 'banana', 'orange']

Example 3: Split a string using multiple spaces

str3 = "Python is   easy"
result = str3.split()  # 使用多个空格作为分隔符
print(result)

Output result:

['Python', 'is', 'easy']

Example 4: Specify the maximum number of splits

str4 = "apple,banana,orange,lemon,grape"
result = str4.split(',', 2)  # 使用逗号作为分隔符，最多拆分为两个子串
print(result)

Output results:

['apple', 'banana', 'orange,lemon,grape']

Summary:
Through the above example, we can see that when writing a Python program, use split The () function can easily split a string into multiple substrings. As needed, we can specify different delimiters and the maximum number of splits to achieve different splitting effects. Mastering the use of the split() function will help us handle string operations more flexibly.
