Change that import to  from matplotlib pyplot import     Note that this style of imports  from X import    is generally discouraged  I would recommend using the following instead   import matplotlib pyplot as plt plt plot  1 2 3 4

If you want to use a function form a package or module in python you have to import and reference them  For example normally you do the following to draw 5 points   1 5   2 4   3 3   4 2   5 1   in the space   import matplotlib pyplot matplotlib pyplot plot  1 2 3 4 5   5 4 3 2 1   bx   matplotlib pyplot show     In your solution   from matplotlib import    This imports the package matplotlib and  plot is not defined  means there is no plot function in matplotlib you can access directly  but instead if you import as  from matplotlib pyplot import   plot  1 2 3 4 5   5 4 3 2 1   bx   show     Now you can use any function in matplotlib pyplot without referencing them with matplotlib pyplot   I would recommend you to name imports you have  in this case you can prevent disambiguation and future problems with the same function names  The last and clean version of above example looks like   import matplotlib pyplot as plt plt plot  1 2 3 4 5   5 4 3 2 1   bx   plt show
