34 How to Access Values (Characters and Substrings) in Strings

35 How to Remove Characters and Strings

36 How to Update Strings

37 ID Check

38 If the replacement field is part of a word, the name must be enclosed in braces

39 In

40 In is case sensitive

41 In order to insert a dollar sign, use $$

42 Index from right

43 Index with offset

44 Interpolating Variables Inside Strings

45 Introducing ljust

46 Introducing StringIO

51 Membership (in, not in)

52 Normal to Unicode

53 Print paired with the string format operator ( % )

54 Range() with len() for indexing into a string

55 Raw string

56 Raw Strings dont treat the backslash as a special character

57 Replacing a substring

58 Repr creates a string that is a representation of the value as a legal Python expression

59 Right justify

60 Rindex with index

61 Runtime String Concatenation

62 Search and Replace in Strings

63 Searching from end of string

64 Searching strings for a substring

65 Searching Strings for Specific EndingsBeginnings

66 Searching Strings for Substrings

67 Signs, Alignment, and Zero-Padding

68 Single-Quoted Strings and Escaping Quotes

69 Slice a string

70 Specify which characters are to be stripped, by listing them all in a string parameter

71 Split by

72 Split is the inverse of join, and is used to split a string into a sequence

73 Split lines

74 Split Without Arguments

75 Splitting Strings

76 Storing Non-ASCII Characters

77 Str converts a value into a string

78 String format

79 String formatting

80 String Formatting Conversion Types

81 String formatting is done with the string formatting operator, the percent (%) sign

82 String Formatting vs Concatenating

83 String literals and other sequence literals may be indexed directly, without using a variable to refer to them

84 String variable

85 String-formatting codes

86 Strings are compared according to their order when sorted alphabetically

87 Strip leading and trailing characters

88 Strip tabs

89 Strip trailing spaces

90 Stripping whitespace from a string

91 Take a string and display it in a loop

92 Template strings

93 Template systems (in this case using HTML)

94 The %e, %f, and %g formats display floating-point numbers in different ways, as the following interaction demonstrates

95 The find method finds a substring within a larger string

96 The lower method returns a lowercase version of the string

97 The replace method returns a string where all the occurrences of one string have been replaced by another

98 The strip method returns a string where whitespace on the left and right (but not internally) has been stripped (removed)

99 The syntax for using the format operator is as follows

100 To check whether a value can be found in a sequence, you use the in operator

101 To clear or remove a string, you assign an empty string or use the del statement, respectively

102 To ignore the difference between uppercase and lowercase letters, use the string methods upper or lower

103 To write a string that spans several lines, you can use triple quotes instead of ordinary quotes

104 Token splitting and delimiter joining

105 Translate replaces parts of a string, translate only works with single characters

106 Triple Quotes

107 Unicode Strings

108 Unicode to normal

109 Use the string format operator ( % ), or put all of the substrings in a list, and using one join() call to put them all together.tx

110 Useful Values from the string Module

111 Using None as an index has the same effect as a missing index

112 When either a starting or an ending index is missing, they default to the beginning or end of the string, respectively

113 Width and Precision

114 You can supply the value-name pairs in a dictionary
