[Basic Grammar] Python Casting

• Type Conversion 

You can convert from one type to another with th int(), float(), and complex. 

 

Example 

Convert from one type to another. 

x = 1    # int
y = 2.8  # float
z = 1j   # complex

#convert from int to float:
a = float(x)

#convert from float to int:
b = int(y)

#convert from int to complex:
c = complex(x)

print(a)
print(b)
print(c)

print(type(a))
print(type(b))
print(type(c))

 

• Specify a variable type 

• Integers: 

x = int(1)   # x will be 1
y = int(2.8) # y will be 2
z = int("3") # z will be 3

• Floats:

x = float(1)     # x will be 1.0
y = float(2.8)   # y will be 2.8
z = float("3")   # z will be 3.0
w = float("4.2") # w will be 4.2

• Strings:

x = str("s1") # x will be 's1'
y = str(2)    # y will be '2'
z = str(3.0)  # z will be '3.0'
