. #To convert a numeriacal string into integer/float we use the syntax:. if we add a float value with an integer we get back an answer in #two strings can be concatenated using + operator. #for example, the integer value in the above example 123 can be converted into a string '123' and then added to concatenate both the strings.">

# Finding the Type of Variable in Python and Their Conversions

In order to find out about the type of 'variable', we use the "type" function.

Consider the following example:

```variable1= 'hello' variable2 = 'world'variable3= 34variable4=43.50print(type(variable1))
print(type(variable2))
print(type(variable3))
print(type(variable4))```
`Output<class 'str'><class 'str'><class 'int'><class 'float'>`

`# if we add a float value with an integer we get back an answer in <class 'float'>#two strings can be concatenated using + operator.#for example,print('hello'+'world')`
`Output:helloworld              #It is to be noted that there is no space produced between the two strings`

`#a string and an integer/float cannot be operated together.print('hello' + 123)`
`Output ERROR: class mismatch`

`# the integer value in the above example 123 can be converted into a string '123' and then added to concatenate both the strings.print('hello' + ' ' + '123')           # a space can also be added as a string in between.`
`Output:hello 123`

`#To convert a numeriacal string into integer/float we use the syntax:variable1= '12345'                                     # its declared as a string.variable2 = int(variable1)                       #The string is converted into a integer of value 12345.variable3 = str(variable2)                       # the integer of value 12345 is now converted into a string '12345'variable4 = 'hello123'                               # alphanumeric string is declaredprint(int(variable4))                                    # a string which is not completly numeric cannot be numeric cannot be converted into integer/float.`
