Loops in Think Python<\/a><\/h2>\n

Loops with “for”<\/h2>\n

Python provides a clean iteration syntax. Note the colon and indentation.<\/p>\n

Example<\/strong><\/p>\n

>> for<\/span> i in<\/span> range(0<\/span>, 3<\/span>):\n>>     print<\/span>(i*2<\/span>)\n0<\/span>\n2<\/span>\n4\n<\/span><\/code><\/pre>\n
Loops with “while”<\/h2>\n
A While loop permits code to execute repeatedly until a certain condition is met. This is useful if the number of iterations required to complete a task is unknown prior to flow entering the loop.<\/p>\n
Syntax<\/strong><\/p>\n
while<\/span> condition:\n    \/\/do something<\/span><\/code><\/pre>\n
>> looping_needed = True<\/span>\n>>\n>> while<\/span> looping_needed:\n>>     # some operation on data<\/span>\n>>     if<\/span> condition:\n>>          looping_needed = False\n<\/span><\/code><\/pre>
