SyntaxError: invalid syntax for yt module

Question

I am trying to understand the issue that I am having, but I cannot fully get why I am getting these errors, especially since this error states what I think is a false positive. I know that it has something to do with the line: for file in glob.glob('puredef_hdf5_chk_000000')but I am unsure what it might be.

import yt
import glob

for file in glob.glob('puredef_hdf5_chk_000000')
ds=yt.load(file)

slc= yt.ProjectionPlot(ds,'theta','density')
slc= yt.SlicePlot(0.25,p_size=15.0,col="Pink")
slc.set_cmap('density',('Blues'))
slc.annotate_particles(0.25,p_size=12.0,col='Red')
slc.save('tr')

SyntaxError: invalid syntax

Answer 1

You're missing a :

for file in glob.glob('placeholder'): # Make sure you add the ':'
    ... # And indent

Also, the contents inside a for loop needs to be indented one tab

Try this:

import yt
import glob

for file in glob.glob('puredef_hdf5_chk_000000')
    ds=yt.load(file)

    slc.set_cmap('density',('Blues'))
    slc.annotate_particles(0.25,p_size=12.0,col='Red')
    slc.save('tr')
