str.format()
In Python you can format string in a variety of ways.We learned how to use a %format technique in last post. In Python version 2.6 introduced str.format() function which is an improvement over % formatting.
It uses { }, curly braces for replacement fields
spyder_version=3
python_version=2.7
print('I am using Spyder ID {} with Python {}' .format(spyder_version,python_version))
#Output
I am using Spyder ID 3 with Python 2.7
You can access variable using digits starting from {0}-{n} as follows
spyder_version=3
python_version=2.7
print('I am using Python {1} and Spyder IDE {0} for data science ' .format(spyder_version,python_version))
#Output
I am using Python 2.7 and Spyder IDE 3 for data science
