Summary of Common String Formatting Methods in Python [Percentage Sign and format Method]

This article describes common string formatting methods in Python. Shared for everyone's reference, as follows:

【Method 1】Percentage (%) method, similar to C's printf, which requires different types separately.

1, Anonymity tuple. (Recommended to use when there are few parameters)

>>> 'Name: %s, Age: %d' % ('walker', 99)
'Name: walker, Age:99

2, Named dict, the key of the dictionary can be reused.

>>> 'Name: %(name)s, Age: %(age)d, Work experience: %(age)d' % {'name':'walker', 'age':99
'Name: walker, Age:99, Work experience:99

【Method Two】format function, no need to specify the string or numeric type.

1, Anonymity parameters.

>>> 'Name: {0}, Age: {1}'.format('walker', 99)
'Name: walker, Age:99

2, Named parameters, parameters can be reused. (Recommended to use when there are many parameters)

>>> 'Name: {name}, Age: {age}, Work experience: {age}'.format(name='walker', age=99)
'Name: walker, Age:99, Work experience:99
