The basic syntax of using a for-in loop in Python is:<\/p>\n

for<\/span> \u53d8\u91cf in<\/span> \u53ef\u8fed\u4ee3\u5bf9\u8c61:\r\n    # \u5faa\u73af\u4f53\u4ee3\u7801<\/span>\r\n<\/code><\/pre>\n
In this case, an iterable object is a sequence (such as a list, tuple, or string) or an iterable object (such as a dictionary or set), and the variable is the value extracted each time during the loop.<\/p>\n
Here are some examples of for-in loops:<\/p>\n
    \n
  1. Iterate through the list:<\/li>\n<\/ol>\n
    fruits = [\"apple\"<\/span>, \"banana\"<\/span>, \"cherry\"<\/span>]\r\nfor<\/span> fruit in<\/span> fruits:\r\n    print<\/span>(fruit)\r\n<\/code><\/pre>\n
      \n
    1. Iterate through the string.<\/li>\n<\/ol>\n
      text = \"Hello\"<\/span>\r\nfor<\/span> letter in<\/span> text:\r\n    print<\/span>(letter)\r\n<\/code><\/pre>\n
        \n
      1. Iterate through the keys of the dictionary.<\/li>\n<\/ol>\n
        person = {\"name\"<\/span>: \"Alice\"<\/span>, \"age\"<\/span>: 25<\/span>}\r\nfor<\/span> key in<\/span> person:\r\n    print<\/span>(key)\r\n<\/code><\/pre>\n
          \n
        1. Iterate over the values of a dictionary.<\/li>\n<\/ol>\n
          person = {\"name\"<\/span>: \"Alice\"<\/span>, \"age\"<\/span>: 25<\/span>}\r\nfor<\/span> value in<\/span> person.values():\r\n    print<\/span>(value)\r\n<\/code><\/pre>\n
            \n
          1. Iterating through the key-value pairs of a dictionary:<\/li>\n<\/ol>\n
            person = {\"name\"<\/span>: \"Alice\"<\/span>, \"age\"<\/span>: 25<\/span>}\r\nfor<\/span> key, value in<\/span> person.items():\r\n    print<\/span>(key, value)\r\n<\/code><\/pre>\n
            I hope these examples can help you understand how to use for-in loops in Python.<\/p>\n","protected":false},"excerpt":{"rendered":"
