61 | <P> | |
62 | Python supports string literals and various numeric literals: | |

83 | <P> | |
84 | Evaluation of a literal yields an object of the given type (string, | |
85 | integer, long integer, floating point number, complex number) with the | |
86 | given value. The value may be approximated in the case of floating | |
87 | point and imaginary (complex) literals. See section <A href="literals.html#literals">2.4</A> | |
88 | for details. | |
89 | ||
90 | <P> | |
91 | All literals correspond to immutable data types, and hence the | |
92 | object's identity is less important than its value. Multiple | |
93 | evaluations of literals with the same value (either the same | |
94 | occurrence in the program text or a different occurrence) may obtain | |
95 | the same object or a different object with the same value. | |
