Invalid Syntax - Ricy - Aug 20, 2017
Hi, I am using a script for a school project but as soon as I try to execute it I get this error :
File "python", line 47
print "Block #{}\n has been added to the blockchain" .format(block_to_add.index)
SyntaxError: invalid syntax
*this being pointed to be wrong
Python Says theres something wrong with the following 2 lines :
print "Block #{}\n has been added to the blockchain" .format(block_to_add.index)
print "Hash: {}\n " .format(block_to_add.hash)
[/b]
Someone who can help me out? Thanks!

-Probably- you are using python3 and on the example you are using python2 syntax.On python2 print is statement and on python3 its function you should use brackets.

you forgot the index value
print "Block #{0}\n has been added to the blockchain" .format(block_to_add.index)
print "Hash: {0}\n " .format(block_to_add.hash)

Check which version of Python you're using.

Format indexes are optional, actually.
OP:
Code
print("Block #{}\n has been added to the blockchain" .format(block_to_add.index))
print("Hash: {}\n " .format(block_to_add.hash))In Python 3.x `print` is a function so you have to call it as such.
