Basic Analysis of Python-Process Control

The Python programming language is very powerful, and its convenient application features also play a very important role for developers. Here, we can first begin to understand the concepts related to the keywords of Python process control, so as to initially master the characteristics of this language. The role of the Python programming language is very powerful, in addition, its convenient application features also play a significant role for developers. Here we can first understand the concepts related to the keywords of Python process control, so as to grasp the characteristics of this language.

Python is an interpreted, object-oriented, and dynamic data type high-level programming language.

Python was invented by Guido van rosum at the end of 1989. The first public release was released in 1991.

Like Perl, Python source code also complies with the GPL (GNU General Public License) protocol.

Which language has flow control, that is, if switch while statements.

The principle and function of distance control for each language are similar, but the expressions are different.

Today I will share with you a Python statement, such as conditions and loops.

Here, we will not use braces, but code blocks.

Note the colon after if and else:

If

name = raw_input("What is your name? ")if(name.endswith('Gumby')):print 'Hello, Mr. Gumby'

Else

name = raw_input("What is your name? ")if(name.endswith('Gumby')):print 'Hello, Mr. Gumby'else:print 'Hello, Stranger'

Elif

Note that the else if statement we use in C ++ is directly written in Python: elif

num = input('Enter a number: ')if num >0 :print 'The number is positive'elif num < 0:print 'The number is negative'else:print '0'

While

x = 1while x <= 100print xx += 1

For Loop

If you can use for, try to avoid using while

words = ['this', 'is', 'an', 'ex', 'parrot']for word in words:print word

For dictionary Traversal

d = {'x':1, 'y':2, 'z':3}for key in d:print key, 'corresponds to', d[key]

Zip and row Iteration

names = ['name', 'beth', 'george', 'damo']ages = [12, 45, 32, 99]for name, age in zip(names, ages):print name, 'is', age, 'years old'

Break bounce cycle

Now, I will introduce you to the basic Python-Process Control editor, and hope to help you!
