In Python it is possible to convert data types to other data types. The method int()
converts a number or string to an integer, or return 0 if no arguments are given. If x
is a number, return x.__int__()
. For floating point numbers, this truncates towards zero.
If x is not a number or if base is given, then x must be a string, bytes, or bytearray instance representing an integer literal in the given base. The literal can be preceded by ‘+’ or ‘-‘ and be surrounded by whitespace. The base defaults to 10. Valid bases are 0 and 2-36. Base 0 means to interpret the base from the string as an integer literal.
Here, x
can be a number or a string. If x
is a number, it can be an integer, a float, or a complex number. If x
is a string, it must contain a numeric value, and an optional prefix indicating the base of the number.
int(x)
intNumber = 12
floatNumber = 1.2
numStr = '12'
numChar = '4'
a = intNumber + int(floatNumber)
b = int(numStr) + intNumber
c = int(numChar)
print("data types of a, b and c: " + str(type(a))
+ str(type(b)) + str(type(c)))
print("value of a " + str(a))
print("value of b " + str(b))
print("value of c " + str(c))
data types of a, b and c: <class 'int'><class 'int'><class 'int'>
value of a 13
value of b 24
value of c 4
intNumber = 12
floatNumber = 1.2
numStr = '12'
numChar = '4'
These lines define four variables: intNumber
is an integer with value 12
, floatNumber
is a floating-point number with value 1.2
, numStr
is a string with value '12'
, and numChar
is a string with value '4'
.
a = intNumber + int(floatNumber)
In this line, floatNumber
is first converted to an integer using the int
function, which rounds down to the nearest whole number (in this case, 1
). Then, intNumber
and the converted floatNumber
are added together, and the result is stored in the variable a
.
b = int(numStr) + intNumber
In this line, numStr
is first converted to an integer using the int
function, which returns the integer value of the string (in this case, 12
). Then, intNumber
and the converted numStr
are added together, and the result is stored in the variable b
.
c = int(numChar)
In this line, numChar
is converted to an integer using the int
function, which returns the integer value of the string (in this case, 4
). The result is stored in the variable c
.
print("data types of a, b and c: " + str(type(a))
+ str(type(b)) + str(type(c)))
print("value of a " + str(a))
print("value of b " + str(b))
print("value of c " + str(c))
These lines print the data type and value of the variables a
, b
, and c
. The type
function is used to get the data type of each variable, and the str
function is used to convert the data type and value to a string so that they can be concatenated with the string "data types of a, b and c: "
, "value of a "
, and "value of b "
. The output shows that all three variables are of type int
and have the values 13
, 24
, and 4
, respectively.
