Common reasons for formatting output using python

This article summarizes some simple and basic formats of output formatting. I will not talk about them here. let's take a look at the details. 1. print the string & gt; print & quot; Im % s & quot; % (& quot; jihite & quot ;) imjihite 2. print integer & gt; print & quot; Im % dyearsold & quot; % (17) Im17yearsold 3. print floating point & gt; & gt; print & quot; π % f & quot; % (3.1415926) π 3 This article summarizes some simple and basic output formatting formats, let's take a look at the detailed introduction.
I. print strings

>>> print "I'm %s" % ("jihite")I'm jihite

II. print the integer

>>> print "I'm %d years old" % (17)I'm 17 years old

3. print floating point numbers

>>> print "π=%f" % (3.1415926)π=3.141593

4. print the floating point number (specify the number of decimal points to be retained)

>>> print "π=%.3f" % (3.1415926)π=3.142

5. specify the placeholder width

>>> print "NAME:%8s AGE:%8d WEIGHT:%8.2f" % ("jihite", 17, 62.2)NAME: jihite AGE:   17 WEIGHT:  62.20

6. specify the placeholder width (left aligned)

>>> print "NAME:%-8s AGE:%-8d WEIGHT:%-8.2f" % ("jihite", 17, 62.2)NAME:jihite  AGE:17    WEIGHT:62.20

7. specify a placeholder (only 0 can be used as a placeholder)

>>> print "NAME:%-8s AGE:%08d WEIGHT:%08.2f" % ("jihite", 17, 62.2)NAME:jihite  AGE:00000017 WEIGHT:00062.20

8. Scientific notation

>>> format(0.0000023, '.2e')'2.30e-06'>>> format(0.23, '.2e')'2.30e-01'
