This article introduces the exp () method used in the calculation of indices in Python, which is the basic method in the introduction of Python, and can be consulted by friends.

The exp () method returns the exponential X:ex.

Grammar

The following is the syntax for the exp () method:

?

1 2 3 | Import math Math.exp (x) |

Note: This function is not directly accessible, so we need to import the math module, and then we need to call this function with the static object of math.

Parameters

X--This is a numeric expression

return value

This method returns the exponent X:ex.

Example

The following example shows the use of the exp () method.

?

1 2 3 4 5 6 7 8 | #!/usr/bin/python Import Math # This would import Math module print ' Math.exp ( -45.17): ", Math.exp ( -45.17) print" MATH.E XP (100.12): ", Math.exp (100.12) print" Math.exp (100.72): ", Math.exp (100.72) print" Math.exp (119L): ", Math.exp (119L) p Rint "Math.exp (Math.PI):", Math.exp (Math.PI) |

When we run the above program, it produces the following results:

?

1 2 3 4 5 | Math.exp ( -45.17): 2.41500621326e-20 math.exp (100.12): 3.03084361407e+43 math.exp (100.72): 5.52255713025e+43 math.exp (119L): 4.7978133273e+51 math.exp (Math.PI): 23.1406926328 |
