Python Print and strip

Errors were made when using these two modules, summarized as follows:

1.print

Print will automatically add line breaks when printing, for example:

 for  in xrange (1,5): ...      Print  1234

If you want to block line breaks, add a comma to the argument, and the print is separated by a space, for example:

 for  in xrange (1,5): ...      Print  1 2 3 4

2.strip ()

Split is the whitespace character that is used to remove the first of the string, and the whitespace characters include tab, space, and line breaks, so note that if you do not want to replace tab, specify the removed character to display.

For example:

>>> str1 = ' abc        ' >>> str1.strip () ' ABC '

>>> str1 ' abc ' >>> Str1.strip (' a ')

In actual code writing, remember to note the location of the whitespace you need to remove, and if the knowledge removes whitespace characters from one end, use:

Lstrip (): Remove whitespace characters from the beginning of the string

Rstrip (): Remove whitespace characters at the end of a string

When writing a mapreduce program, you often want to slice and remove whitespace characters, especially when you want to pay attention to these details.
