Easygui. msgbox ("Hello there! ") Error: Tcl_Init error: Can't find a usable init. tcl in the following directories solution, includedirectories Today, I learned about Parent and Child programming. When I saw the first gui running (the Code is as follows ): 1 import easygui2 easygui.msgbox("Hello there!") The following error is reported: Tcl Init error: Can't find a usable init.

L errorinfo: -- error messageIf the program is wrong, the TCL parser will give the error back to the application, and the program decides what to do with it. If there are no other measures, the error message will usually be printed on the screen, and this is errorinfo responsible for processing.L ErrorCode: -- error codeTCL provides another global variable, errorcode, which provides information about the error condition. The format is easily handled

The biggest advantage of Modelsim's Tcl is that it allows the entire simulation to run automatically, saving you from the trouble of performing various user interface control operations each time. With TCL, You can automatically create databases, map databases to physical directories, and compileSource code, Start the simulator, run the simulation and a series of other operations. The following describes t

　　expr is for Tcl-to-do math type operations. It takes all of its arguments ("2 + 2" for example) and evaluates the result as a Tcl "expression", and returns the value. Many commands expr use behind the scenes of order if to evaluate test expressions, such as, and loops. for tip: enclosing the arguments to in expr curly braces would result in faster code. So do expr{$i*10} instead of simplyexpr$i*
