Printing variables in Python 3.4

Question

So the syntax seems to have changed from what I learned in Python 2... here is what I have so far

for key in word:
    i = 1
    if i < 6:
        print ( "%s. %s appears %s times.") % (str(i), key, str(wordBank[key]))

The first value being an int, the second a string, and the final an int.

How can I alter my print statement so that it prints the variables correctly?

Solution 1

Version 3.6+: Use a formatted string literal, f-string for short

print(f"{i}. {key} appears {wordBank[key]} times.")

Solution 2

Try the format syntax:

print ("{0}. {1} appears {2} times.".format(1, 'b', 3.1415))

Outputs:

1. b appears 3.1415 times.

The print function is called just like any other function, with parenthesis around all its arguments.

Solution 3

You can also format the string like so:

>>> print ("{index}. {word} appears {count} times".format(index=1, word='Hello', count=42))

Which outputs

1. Hello appears 42 times.

Because the values are named, their order does not matter. Making the example below output the same as the above example.

>>> print ("{index}. {word} appears {count} times".format(count=42, index=1, word='Hello'))

Formatting string this way allows you to do this.

>>> data = {'count':42, 'index':1, 'word':'Hello'}
>>> print ("{index}. {word} appears {count} times.".format(**data))
1. Hello appears 42 times.

Solution 4

The problem seems to be a mis-placed ). In your sample you have the % outside of the print(), you should move it inside:

Use this:

print("%s. %s appears %s times." % (str(i), key, str(wordBank[key])))
