Python Numbers

In Python, numbers are of the following data types:

• int
• float
• complex

 

int

int is a positive or a negative integer of any length. int should not be a decimal or a fraction.

Example:

int1 = -2345698
int2 = 0
int3 = 100548

print(type(int1))
print(type(int2))
print(type(int3))

Output:

<class 'int'>
<class 'int'>
<class 'int'>

 

Float

A float is a positive or a negative decimal number. It can be an exponential number or a fraction.

Example:

flt1 = -8.35245     #decimal number
flt2 = 0.000001     #decimal number
flt3 = 2.6E44       #exponential number
flt4 = -6.022e23    #exponential number

print(type(flt1))
print(type(flt2))
print(type(flt3))
print(type(flt4))

Output:

<class 'float'>
<class 'float'>
<class 'float'>
<class 'float'>

 

complex

Complex numbers are a combination of real and imaginary number. They are of the form a + bj, where a is the real part and bj is the imaginary part.

Example:

cmplx1 = 2 + 4j
cmplx2 = -(3 + 7j)
cmplx3 = -4.1j
cmplx4 = 6j

print(type(cmplx1))
print(type(cmplx2))
print(type(cmplx3))
print(type(cmplx4))

Output:

<class 'complex'>
<class 'complex'>
<class 'complex'>
<class 'complex'>
