Let\u2019s do some loops!<\/p>\n\n\n\n

The general format is<\/p>\n\n\n\n

For (single item of range) in range:
do stuff<\/p>\n\n\n\n

Note the colon and the tab in the next line here too! Just like \u2018if\u2019 code.<\/p>\n\n\n\n

  1. Type and run<\/li><\/ol>\n\n\n\n

    cousinsAge = [16, 19, 19, 22, 23, 27, 27, 33, 35, 40]<\/strong><\/p>\n\n\n\n

    for age in cousinsAge:
    print(age)<\/strong><\/p>\n\n\n\n

    Note the \u2018age\u2019 variable in the for loop. It is a loop variable that takes turn to contain each variable in the list as we loop through it<\/p>\n\n\n\n

    It is not the index like is C++, or a loop variable that only exists in a loop. It is true that its existence start with the for loop call \u2013 but if you print it later outside the loop you will notice that it quietly continues to exist holding the last value it captured (in the last iteration)<\/p>\n\n\n\n

    We can use any variable name instead of age. Let\u2019s do a bit more of the same\/similar thing \u2013 so that we understand.<\/p>\n\n\n\n

    1. Type and run<\/li><\/ol>\n\n\n\n

      for eachItem in cousinsAge:
