Python complex numbers consist of two parts such as real and imaginary numbers, it also allows us to access these separately. This is useful when you want to extract a specific part of a complex number. z = 3 + 4j print(z.real) print(z.imag) Output: 3.0 4.0 You can see the output...
inf) # Complex number: zero real part and positive infinity imaginary part print("Positive complex infinity:", cmath.infj) # Not a number value print("NaN value:", cmath.nan) # Complex number: zero real part and NaN imaginary part print("NaN complex value:", cmath.nanj) ...
For example, complex('1+2j') is fine, but complex('1 + 2j') raises ValueError. 说明: 1. 函数功能,返回一个复数。有两个可选参数。 2. 当两个参数都不提供时,返回复数 0j。 >>> complex() 0j 3. 当第一个参数为字符串时,调用时不能提供第二个参数。此时字符串参数,需是一个能表示复数...
5.42is a floating-point number. Complex numbers are written in the form,x + yj, wherexis the real part andyis the imaginary part. We can use thetype()function to know which class avariableor a value belongs to. Let's see an example, num1 =5print(num1,'is of type', type(num1)...
z = 1j# complex To verify the type of any object in Python, use thetype()function: Example print(type(x)) print(type(y)) print(type(z)) Try it Yourself » Int Int, or integer, is a whole number, positive or negative, without decimals, of unlimited length. ...
Note When converting from a string, the string must not contain whitespace around the central + or - operator. For example, complex('1+2j') is fine, but complex('1 + 2j') raises ValueError. The complex type is described in Numeric Types — int, float, long, complex. ...
The algebraic form of a complex number follows the standard rules of algebra, which is convenient in performing arithmetic. For example, addition has a commutative property, which lets you swap the order of the two parts of a complex number literal without changing its value:...
