Python Ex7 syntax error keyword can't be an expression

#1

I have typed Zed’s code like this

print(“Mary had a little lamb.”)
print(“Its fleece was white as {}.”.format(‘snow’))
print(“And everywhere that Mary went.”)
print("." * 10) #what did that do?

end1 = “C”
end2 = “h”
end3 = “e”
end4 = “e”
end5 = “s”
end6 = “e”
end7 = “B”
end8 = “u”
end9 = “r”
end10 = “g”
end11 = “e”
end12 = “r”

#watch that comma at the end. try removing it to see what happens
print(end1 + end2 + end3 + end4 + end5 + end6 + end=’ ')
print(end7 + end8 + end9 + end10 + end11 + end12)

And I keep getting this error message (wirh or without the comma)
PS C:\Users\setup\lpthw> python ex7.py
File “ex7.py”, line 20
print(end1 + end2 + end3 + end4 + end5 + end6, + end=’’)
^

You have this line:

print(end1 + end2 + end3 + end4 + end5 + end6, + end=’’)

But there is no plus before end=’’ so change it to this:

print(end1 + end2 + end3 + end4 + end5 + end6, end=’’)
#3

Thanks, that is so obvious once you point it out. I did read it backwards multiple times, but did not see it. Practice, practice, practice.

#4

You wouldn’t believe how frustrating single character errors are. I’ve been blocked for weeks because of a stray quote or a single misspelled word.

#5

Hi, but what does this line mean exactly?
SyntaxError: keyword can’t be an expression

#6

They’re saying you can use the keyword “print” in an expression, but really that message is totally useless. What causes it is the end of the line:

end + end="")

Which confuses Python and it keeps on reading it into the next line. So, Python thinks you actually typed this:

end + end="")print(end

Which is meaningless garbage, and then python just gives up and tells you a garbage error. The solution is simple though:

end, end="")

See the comma? That’s all.
