Either something like this    abc    str 9    or    abs 0   format 9    or   abs d     9

You have to convert the int into a string    abc    str 9

If it worked the way you expected it to  resulting in  abc9    what would  9    9 deliver  18 or  99    To remove this ambiguity  you are required to make explicit what you want to convert in this case    abc    str 9

Since Python is a strongly typed language  concatenating a string and an integer as you may do in Perl makes no sense  because there s no defined way to  quot add quot  strings and numbers to each other   Explicit is better than implicit      says  quot The Zen of Python quot   so you have to concatenate two string objects  You can do this by creating a string from the integer using the built-in str   function   gt  gt  gt   quot abc quot    str 9   abc9   Alternatively use Python s string formatting operations   gt  gt  gt   abc d    9  abc9   Perhaps better still  use str format     gt  gt  gt   abc 0   format 9   abc9   The Zen also says   There should be one-- and preferably only one --obvious way to do it   Which is why I ve given three options  It goes on to say     Although that way may not be obvious at first unless you re Dutch
