syntaxerror: “unexpected character after line continuation character in python” math

Question

I am having problems with this Python program I am creating to do maths, working out and so solutions but I'm getting the syntaxerror: "unexpected character after line continuation character in python"

this is my code

print("Length between sides: "+str((length*length)*2.6)+" \ 1.5 = "+str(((length*length)*2.6)\1.5)+" Units")

My problem is with \1.5 I have tried \1.5 but it doesn't work

Using python 2.7.2

Answer 1

The division operator is /, not \

Answer 2

The backslash \ is the line continuation character the error message is talking about, and after it, only newline characters/whitespace are allowed (before the next non-whitespace continues the "interrupted" line.

print "This is a very long string that doesn't fit" + \
      "on a single line"

Outside of a string, a backslash can only appear in this way. For division, you want a slash: /.

If you want to write a verbatim backslash in a string, escape it by doubling it: "\\"

In your code, you're using it twice:

 print("Length between sides: " + str((length*length)*2.6) +
       " \ 1.5 = " +                   # inside a string; treated as literal
       str(((length*length)*2.6)\1.5)+ # outside a string, treated as line cont
                                       # character, but no newline follows -> Fail
       " Units")

Answer 3

The division operator is / rather than \.

Also, the backslash has a special meaning inside a Python string. Either escape it with another backslash:

"\\ 1.5 = "`

or use a raw string

r" \ 1.5 = "

Answer 4

You must press enter after continuation character

Note: Space after continuation character leads to error

cost = {"apples": [3.5, 2.4, 2.3], "bananas": [1.2, 1.8]}

0.9 * average(cost["apples"]) + \ """enter here"""
0.1 * average(cost["bananas"])

Answer 5

Well, what do you try to do? If you want to use division, use "/" not "\". If it is something else, explain it in a bit more detail, please.

Answer 6

As the others already mentioned: the division operator is / rather than **. If you wanna print the ** character within a string you have to escape it:

print("foo \\")
# will print: foo \

I think to print the string you wanted I think you gonna need this code:

print("Length between sides: " + str((length*length)*2.6) + " \\ 1.5 = " + str(((length*length)*2.6)/1.5) + " Units")

And this one is a more readable version of the above (using the format method):

message = "Length between sides: {0} \\ 1.5 = {1} Units"
val1 = (length * length) * 2.6
val2 = ((length * length) * 2.6) / 1.5
print(message.format(val1, val2))
