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?
The syntax has changed in that print
is now a function. This means that the %
formatting needs to be done inside the parenthesis:1
print("%d. %s appears %d times." % (i, key, wordBank[key]))
However, since you are using Python 3.x., you should actually be using the newer str.format
method:
print("{}. {} appears {} times.".format(i, key, wordBank[key]))
Though %
formatting is not officially deprecated (yet), it is discouraged in favor of str.format
and will most likely be removed from the language in a coming version (Python 4 maybe?).
1Just a minor note: %d
is the format specifier for integers, not %s
.
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])))
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.
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.
one can print values using the format method in python. This small example will help take input of two numbers a and b. Print a+b in first line and a-b in second line
print('{:d}\n{:d}'.format(a+b,a-b))
Similarly in the answer we can do
print ("{0}. {1} appears {2} times.".format(22, 'c', 9999))
The python method format() for string is used to specify a string format. So {0},{1},{2} are like array indexes called as positional parameters. Therefore {0} is assigned first value written in format (a+b), {1} is assigned the second value (a-b) and so on. We can also use keyword instead of positional parameter like for example
print("Hi! my name is {name}".format(name="rashi"))
Therefore name here is the keyword and its value is Rashi Hope it helps :)
Version 3.6+: Use a formatted string literal, f-string for short
print(f"{i}. {key} appears {wordBank[key]} times.")
