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  lt  6          print    quot  s   s appears  s times  quot      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

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 :)

You can also format the string like so    gt  gt  gt  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    gt  gt  gt  print    index    word  appears  count  times  format count 42  index 1  word  Hello      Formatting string this way allows you to do this    gt  gt  gt  data     count  42   index  1   word   Hello    gt  gt  gt  print    index    word  appears  count  times   format   data   1  Hello appears 42 times

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

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
