0 Fundamentals python-7.1 String Introduction and common functions in Python

In Python, the string becomes a powerful set of processing tools, and he is immutable, meaning that the string contains the order of characters and characters, which he cannot modify

The string is a slightly larger category of objects that we need to learn later-the first representation of a sequence

In the section of the string about the operation of the sequence, the following list is the same as the tuple

Some of the operations and functions commonly used in strings

Operation	Explain
S= "	Empty string
s= "ABC ' d"	Double quotes and single quotes are the same
s= ' abc\n '	Escape sequences, use variables to fully display characters, Only use the print function to show escape
S= "" "AAAAA" ""	Sanchong Quote String block
S=r ' \temp\spam '	Raw string
S=b ' abc '	Python 3.x byte string
S=u ' BAC '	Unicode string
S1+s2	Merge
S*3	Repeat
S[i]	Index
S[I:J]	Sharding
Len (s)	Request length
"A%s parrot"% kind	String formatting expressions
"A {0} parrot". Format (Kind)	Method of String formatting
S.find (' xxx ')	Search
S.rstrip ()	Remove spaces
S.replace (' xxx ', ' xxx ')	Replace
S.endswith (' xxx ')	End With XXX
' xxx '. Join (Strlist)	Entry and exit separators
S.encode (' latin-1 ')	Change code
For x in S:print (x)	Iteration

Right here, thank you.
