# The Z3 Python API requires libz3.dll/.so/.dylib in the 
# PATH/LD_LIBRARY_PATH/DYLD_LIBRARY_PATH
# environment variable and the PYTHONPATH environment variable
# needs to point to the `python' directory that contains `z3/z3.py'
# (which is at bin/python in our binary releases).

# If you obtained example.py as part of our binary release zip files,
# which you unzipped into a directory called `MYZ3', then follow these
# instructions to run the example:

# Running this example on Windows:
# set PATH=%PATH%;MYZ3\bin
# set PYTHONPATH=MYZ3\bin\python
# python example.py

# Running this example on Linux:
# export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:MYZ3/bin
# export PYTHONPATH=MYZ3/bin/python
# python example.py

# Running this example on macOS:
# export DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:MYZ3/bin
# export PYTHONPATH=MYZ3/bin/python
# python example.py

x = Real('x')

s.add(x + y > 4, x > 1, y > 1)
