    jewelry boxes wholesale los angeles The vertical line "|" means or meaning. It means that the two matching conditions are used for logical "or" (or) operations.
    , for example, Him | Her) matches "It Belongs to Him" ​​and "It Belongs to Her", but it cannot match "It Belongs to them.". Note: This meta character is not supported by all software.
    The simplest Yuan character is the point, which can match any single character (note that it does not include changing the character).

    extension information:
    D value for value:

    The operating rules of the logical operator itself must also follow the two principles below:
    1. Solving the logical expression from left to right.
    2, short circuit principle: During the solution of logical expression, as long as the values ​​of the logical expression can be determined at any time, the solution process will not be performed and the solution is over.
    The specific understanding of logical expression operation rules can be found first in the expression of the lowest priority in the expression, and the entire logical expression is divided into several calculation parts based on these operators.
    In the calculation part on the far left, calculate the value of this part according to the rules of arithmetic operations, relationship operations and logical operations. Each computing part is determined by the logical value of the logical computing tightly on the right of the part on the right.
    If the value of the entire logical expression can be judged, all the subsequent calculations are stopped; the next calculation part of the next calculation part is performed only when the value of the entire logic expression is not determined.

    statement piece jewelry wholesale Just cut the division, the example of Python below
    Nessing needs to be replaced first:
    import re
    inputstr = "[{local = {width = 290, top = 10, left = 78, height = 78, height = 78, height = 78, height = 28}, words = some text}, {local = {width = 290, top = 10, left = 78, height = 28}, words = some text}, {local = {width = 290, top = 10, left = 78, height = 28}, words = some text}, {local = {width = 290, top = 10, left = 78, height = 28}, words = some text}] "
    inputstr.RePlace ("}, {", "}; {")
    = re.Split (r "[|; |]" ", inputStr)
    print ()

    wholesale harry potter jewelry In the regular right, it is expressed in
    The requirements above. AB (1 | 2) can be implemented ~
    ad [12] can also be implemented, but the concept of character set is used

    free shipping china wholesale jewelry [0-9A-Z] [0-9a-z] {0, i}/[0-9a-z] {0,14-I} [0-9a-z] r
    What should I do if I do n’t have a variable? I have never encountered this kind of uncertain rules before (but I really do my best as a reference idea ... I was abused by the compilation principle, so I sympathized with the landlord!

    The answer on the second floor [not feasible] is because "/" also participated in the closure, which leads to "/" zero or multiple times
    qqa/2q/23. R n
    "/" needs to be unclear whether the righteousness is unclear. Considering it by default as needed

    In the name of this software? I want to know ~~ Thank you, thank you
