问题 How do I rectify the error \"unexpected indent\" in python? 回答1: Python uses spacing at the start of the line to determine when code blocks start and end. Errors you can get are: Unexpected indent. This line of code has more spaces at the start than the one before, but the one before is not the start of a subblock (e.g. if/while/for statement). All lines of code in a block must start with exactly the same string of whitespace. For instance: >>> def a(): ... print "foo" ... print "bar"

问题 When issuing a command to MySQL, I\'m getting error #1064 \"syntax error\". What does it mean? How can I fix it? 回答1: TL;DR Error #1064 means that MySQL can't understand your command. To fix it: Read the error message. It tells you exactly where in your command MySQL got confused. Examine your command. If you use a programming language to create your command, use echo , console.log() , or its equivalent to show the entire command so you can see it. Check the manual. By comparing against what

问题 I want to define a two-dimensional array without an initialized length like this: Matrix = [][] but it does not work... I\'ve tried the code below, but it is wrong too: Matrix = [5][5] Error: Traceback ... IndexError: list index out of range What is my mistake? 回答1: You're technically trying to index an uninitialized array. You have to first initialize the outer list with lists before adding items; Python calls this "list comprehension". # Creates a list containing 5 lists, each of 8 items,
