However, there are a few syntax quirks to keep in mind when working with tuples in Python. The section below covers the syntax for each way that you can create a Python tuple. Create a Python Tuple A Python tuple can be created in the following ways: Create an empty tuple with an ...
When we use thelist,tuple, andsetbuilt-in functions on an iterable, we force the iterator to return all items. Note that some iterables can be very large. list_tuple_set.py #!/usr/bin/python text = "an old falcon" data = list(text) print(data) data2 = tuple(text) print(data2)...
#!/usr/bin/python import re words = ('seven', 'even', 'prevent', 'revenge', 'maven', 'eleven', 'amen', 'event') pattern = re.compile(r'.even') for word in words: if re.match(pattern, word): print(f'The {word} matches') In the example, we have a tuple with eight ...
Python S-expression emulation using tuple-like objects. Examples etuples are like tuples: >>> from operator import add >>> from etuples import etuple, etuplize >>> et = etuple(add, 1, 2) >>> et ExpressionTuple((<built-in function add>, 1, 2)) >>> from IPython.lib.pretty im...
Python允许你在list或tuple前面加一个*号,把list或tuple的元素变成可变参数传进去。 1numsp[1, 2, 3]2fun(*nums) *nums表示把nums这个list的所有元素作为可变参数传进去。这种写法相当有用,而且很常见。 4. 关键字参数的使用: 1defprint_person(name, age, **kw):2print('name:', name,'age:', age,...
Python >>>person=dict(zip(fields,values))>>>person{'name': 'John', 'last_name': 'Doe', 'age': '45', 'job': 'Python Developer'} Here, you create a dictionary that combines the two lists.zip(fields, values)returns an iterator that generates 2-items tuples. If you calldict()on...
The two loss function objects are passed as a Python tuple, indicated by the parentheses, but the Learner object is passed as a Python list, indicated by square brackets. You can pass multiple Leaner objects to a Trainer, though the demo program passes just one. The co...
