Format numbers to strings in Python

Question

I need to find out how to format numbers as strings  My code is here   return str hours      str minutes      str seconds      ampm   Hours and minutes are integers  and seconds is a float   the str   function will convert all of these numbers to the tenths  0 1  place   So instead of my string outputting  5 30 59 07 pm   it would display something like  5 0 30 0 59 1 pm    Bottom line  what library   function do I need to do this for me

str   in python on an integer will not print any decimal places   If you have a float that you want to ignore the decimal part  then you can use str int floatValue     Perhaps the following code will demonstrate    gt  gt  gt  str 5   5   gt  gt  gt  int 8 7  8

If you have a value that includes a decimal  but the decimal value is negligible  ie  100 0  and try to int that  you will get an error   It seems silly  but calling float first fixes this   str int float  variable

Python 2 6   It is possible to use the format   function  so in your case you can use   return    02d    02d     2f      format hours  minutes  seconds  ampm    There are multiple ways of using this function  so for further information you can check the documentation   Python 3 6   f-strings is a new feature that has been added to the language in Python 3 6  This facilitates formatting strings notoriously   return f  hours 02d   minutes 02d   seconds  2f   ampm

Starting with Python 3 6  formatting in Python can be done using formatted string literals or f-strings   hours  minutes  seconds   6  56  33 f  hours 02   minutes 02   seconds 02    pm  if hours  gt  12 else  am      or the str format function starting with 2 7      02    02    02      format hours  minutes  seconds   pm  if hours  gt  12 else  am     or the string formatting   operator for even older versions of Python  but see the note in the docs     02d  02d  02d     hours  minutes  seconds    And for your specific case of formatting time  there   s time strftime   import time  t    0  0  0  hours  minutes  seconds  0  0  0  time strftime   I  M  S  p   t

Starting in Python 2 6  there is an alternative  the str format   method  Here are some examples using the existing string format operator        gt  gt  gt   Name   s  age   d      John   35    Name  John  age  35    gt  gt  gt  i   45   gt  gt  gt   dec   d oct    o hex    X     i  i  i    dec  45 oct  055 hex  0X2D    gt  gt  gt   MM DD YY    02d  02d  02d     12  7  41    MM DD YY   12 07 41    gt  gt  gt   Total with tax     2f     13 00   1 0825    Total with tax   14 07    gt  gt  gt  d     web    user    page   42    gt  gt  gt   http   xxx yyy zzz   web s   page d html    d   http   xxx yyy zzz user 42 html     Here are the equivalent snippets but using str format      gt  gt  gt   Name   0   age   1   format  John   35    Name  John  age  35    gt  gt  gt  i   45   gt  gt  gt   dec   0  oct   0  o  hex   0  X   format i    dec  45 oct  0o55 hex  0X2D    gt  gt  gt   MM DD YY    0 02d   1 02d   2 02d   format 12  7  41    MM DD YY   12 07 41    gt  gt  gt   Total with tax    0  2f   format 13 00   1 0825    Total with tax   14 07    gt  gt  gt  d     web    user    page   42    gt  gt  gt   http   xxx yyy zzz  web   page  html  format   d    http   xxx yyy zzz user 42 html    Like Python 2 6   all Python 3 releases  so far  understand how to do both  I shamelessly ripped this stuff straight out of my hardcore Python intro book and the slides for the Intro Intermediate Python courses I offer from time-to-time   -   Aug 2018 UPDATE  Of course  now that we have the f-string feature in 3 6  we need the equivalent examples of that  yes another alternative    gt  gt  gt  name  age    John   35  gt  gt  gt  f Name   name   age   age    Name  John  age  35    gt  gt  gt  i   45  gt  gt  gt  f dec   i  oct   i  o  hex   i  X    dec  45 oct  0o55 hex  0X2D    gt  gt  gt  m  d  y   12  7  41  gt  gt  gt  f MM DD YY    m 02d   d 02d   y 02d    MM DD YY   12 07 41    gt  gt  gt  f Total with tax    13 00   1 0825  2f    Total with tax   14 07    gt  gt  gt  d     web    user    page   42   gt  gt  gt  f http   xxx yyy zzz  d  web     d  page    html   http   xxx yyy zzz user 42 html
