Python records-Getting Started to practice-string manipulation (i)

I follow the book, summarize the implementation to record, do not feel simple to try, knock a code. Executive power is the sword of a good programmer. If you are a novice in mastering other language situations such as Java, C or PHP and so on any kind of basic grammar, the program is all the same, you can follow my record and I will step-by-step learning python.The Scarlet Letter is to pay attention to the place, during python2 and Python3 differences need to note that I will also be Red character logo. 1. Modify String Case

Name="ABC myname"print(Name.title ()) < turn capital Letter >
Print　　(Name.upper ()) < go all caps > Print　　(Name.lower ()) < turn all lowercase >  #输出:
ABC myname
ABC MYNAME
ABC MyName

2. Stitching strings and tabs and line breaks

First_name="py"last_name="Thon"Full_name=first_name+" "+last_name < quotation marks in the middle is a space if you do not add a space, you only need a quotation mark connection >message="Hello,"+full_name.title () +"!"Print(message)
#输出:
Hello,py Thon
-------------------------------------------------------------------------------
Print("ABC\NABC\N\TABC")</n: line-break/t-tab >
#输出:
Abc
Abc
Abc

3. Remove string whitespace

My_name=""My_name.retrip () My_name.lstrip () My_name.strip ()# output:  "  python" "" "Python" 

4. Digital

As with other grammars (+) plus (-) minus (*) multiply (/) divide (*) the second party.

Floating point operations Note that the inclusion of decimal places is indeterminate, such as JavaScript arithmetic floating-point, where many languages can have multiple decimal places, because the numeric type of JavaScript is stored in the 64-bit IEEE 754 format.

can Baidu "python Reserved Decimal place" processing

0.2+0.1
#输出0.30000000000000004

Python2 and python3 floating point arithmetic difference note:

# python2.73/2# output 1#python2.73.0/2# output 1.5#  python33/2# output 1.5

Numeric and string combinations, note that numbers need to be specified as numbers of type int and string combinations to be numeric to string characters

age=23Name="zc"message=" my name is "+name+ STR (age) +" year old "print(message)# output My name is zc23 years old.
