Confused by {} in Python code
#5
It's called string formatting.
The evolution of string formatting.
>>> M = 100
>>> # old don't use
>>> print('M = %d' % M)
M = 100
>>> 
>>> # Python 2.6 we get format()
>>> print('M = {}'.format(M))
M = 100
>>> 
>>> # Python 3.6 we get f-string
>>> print(f'M = {M}')
M = 100
f-string is the future,but format() will be used for a long time.
f-string can take expressions here calculate and upper():
>>> a = 10
>>> b = 20
>>> s = 'correct'
>>> print(f'The sum of a {a} and b {b} is {a+b} {s.upper()}')
The sum of a 10 and b 20 is 30 CORRECT
More about format() PyForamt.
