The for loop in Python is used to iterate over an iterable object (such as a list, tuple, string, etc.) and perform specific operations.<\/p>\n

The grammar format is as follows:<\/p>\n

for \u53d8\u91cf in \u53ef\u8fed\u4ee3\u5bf9\u8c61:\r\n    # \u6267\u884c\u64cd\u4f5c\r\n<\/code><\/pre>\n
In each iteration, a variable is taken from the iterable object to be traversed, the iterable object is the object being traversed, and the operation is the code block to be executed in each iteration.<\/p>\n
Here are some examples of using for loops:<\/p>\n
    \n
  1. Iterating through a 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
    Output:<\/p>\n
    apple\r\nbanana\r\ncherry\r\n<\/code><\/pre>\n
      \n
    1. Iterate through the string.<\/li>\n<\/ol>\n
      message = \"Hello, World!\"<\/span>\r\nfor<\/span> char in<\/span> message:\r\n    print<\/span>(char)\r\n<\/code><\/pre>\n
      Output:<\/p>\n
      H\r\ne\r\nl\r\nl\r\no\r\n,\r\n \r\nW\r\no\r\nr\r\nl\r\nd\r\n!\r\n<\/code><\/pre>\n
        \n
      1. Iterate through the dictionary.<\/li>\n<\/ol>\n
        student = {\"name\"<\/span>: \"Alice\"<\/span>, \"age\"<\/span>: 18<\/span>, \"grade\"<\/span>: \"A\"<\/span>}\r\nfor<\/span> key in<\/span> student:\r\n    print<\/span>(key, \"=\"<\/span>, student[key])\r\n<\/code><\/pre>\n
        Output:<\/p>\n
        name = Alice\r\nage = 18\r\ngrade = A\r\n<\/code><\/pre>\n
          \n
        1. Looping with the range() function:<\/li>\n<\/ol>\n
          for<\/span> i in<\/span> range<\/span>(5<\/span>):\r\n    print<\/span>(i)\r\n<\/code><\/pre>\n
          Output:<\/p>\n
          0\r\n1\r\n2\r\n3\r\n4\r\n<\/code><\/pre>\n
          Here is the basic usage of a for loop, you can add conditional statements, nested loops, etc. within the loop based on specific requirements.<\/p>\n","protected":false},"excerpt":{"rendered":"
