Do you mean

print name.strip()

still prints a leading space? If so, what does 

print repr(name)

print? If it is

"\xc2\xa0Jeff Adrien"


print name.decode("utf-8").strip()

Or do you mean the effect of strip() is not permanent? You have to modify 
the line then:

cleaned_lines = []
for line in positions:
    info = line.split(",")
    info[0] = info[0].strip()
positions = cleaned_lines
