fault tolerance rate: there are several levels of fault tolerance m,l,q,h, the higher the fault tolerance rate, the more effective pixel points of two-dimensional code. Here use lowercase utf-8 encoding, uppercase will appear]q2\000026 beginning content, in order to look at the point also set the margin and size.
Step three: Realize the color two-dimensional code
First look at the effect:
In Linux terminal, ANSI escape sequence to control colorBasic rule: Precede with \033[, end with \033[0m reset to original colorYou can enter the following sentence in the terminal, you can see the output of the green hello.
>>echo-e ' \033[0;32mhello\033[0m '
where 0;32m controls the color.The simplest, as long as the 0;32m in the 2 change to 0-7, it corresponds to different colors.
Using this, in Python, you can do this.
#coding =utf-8 FMT = ' \033[0;3{}m{}\033[0m
elements in the document and perform a reset () on them.Another problem you may have to face is that you don't want certain elements to be selected. JQuery provides the filter () and not () methods to solve this problem. Filter () reduces the selection of non-conforming items by filtering the expression, and not () is used to cancel all selected items that conform to the filter expression. Consider an unordered list, and you want to select all LI elements that have no UL child elements.
