# pyexec

Purpose
Execute Python statements from a string.
Synopsis
`procedure pyexec(code:string)`
Argument

code | Python statements to execute

Example
The following model runs Python statements from a string:

     model "Python script from string"
       uses "python3"
       writeln("Python version:")
       pyexec("import platform; print(platform.python_version())")
     end-model

Further information
1. This function compiles and runs a Python script from a string buffer and waits for its termination. It is a fatal error if the compilation fails or if a Python run-time error occurs.
2. Use the I/O Driver python and the functions pyget and pyset to transfer data between Mosel and Python. Use pyget to evaluate a single expression with return value and use pycall to call a single function with input arguments or return value.
3. Do not concatenate untrusted strings from the end user into the code string. See Section Xpress Insight 5 configuration for more information.
