This article summarizes some simple and basic output formatting forms. I won’t say much below, let’s take a look at the detailed introduction.
1. Print string
>>> print "I'm %s" % ("jihite") I'm jihite
2. Print integer
>>> print "I'm %d years old" % (17) I'm 17 years old
3. Print Floating point number
>>> print "π=%f" % (3.1415926) π=3.141593
4. Print floating point number (specify the number of decimal points to be retained)
>>> print "π=%.3f" % (3.1415926) π=3.142
5. Specify the occupancy 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 the placeholder width placeholder (only 0 can be used as 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'
