Built-in Functions¶

built-in we've used so far: type(), int(), float(), str(), input(), print(), etc.
Python provides a list of built-in functions that are readily available for use:

In [1]:

bin(3)

In [2]:

# If prefix "0b is desired or not, use either of the following ways
print(format(3, '#b'))
print(format(3, 'b'))

returns the string representing a character whose Unicode code point is the integer uniCode
inverse of ord(character)

In [3]:

print(chr(65))
print(chr(97))
print(chr(8364))

In [4]:

globals()

In [5]:

print(hex(42))
print(hex(-42))

In [6]:

# Other ways
format(255, '#x'), format(255, 'x'), format(255, 'X')

In [7]:

print(oct(100))

In [8]:

print(format(10, '#o'))
print(format(10, 'o'))

0o12
12

In [9]:

print(ord(' '))
print(ord('~'))

32
126

In [12]:

x = 10

In [13]:

id(x)

Out[13]:

4341667328

given two non-complex numbers as arguments, return a pair of numbers as tuple consisting of their quotient and remainder using integer division

In [14]:

print(divmod(7, 3)) # return (quotient, remainder)
quotient, remainder = divmod(7, 3)
print(quotient, remainder)

(2, 1)
2 1

In [15]:

y = 2
print(eval('y**2'))
print(eval('y+2*3'))

4
8

In [17]:

print('max=', max(100, 8.9, 999, 1000.5))

max= 1000.5

In [18]:

print('min=', min(100, 8.9, 999, 1000.5))

min= 8.9

In [19]:

print('2 to the power 3 =', pow(2, 3))

2 to the power 3 = 8
