Python Program to Parse a String to a Float or Int

To understand this example, you should have the knowledge of the following Python programming topics:

Example 1: Parse string into integer


              
balance_str = "1500"
balance_int = int(balance_str)

# print the type
print(type(balance_int))

# print the value
print(balance_int)

Output


              
<class 'int'>
1500

int() can be used to parse a string to an integer. The argument passed balance_int is the string. As shown in the above example, you can see the type of the string changed to int.

Note: The string must be a numeral value.

Example 2: Parse string into float


              
balance_str = "1500.4"
balance_float = float(balance_str)

# print the type
print(type(balance_float))

# print the value
print(balance_float)

Output


              
<class 'float'>
1500.4

float() can be used to parse a string to an integer. Similar to Example 1, the string is passed as an argument to float().

Example 3: A string float numeral into integer


              
balance_str = "1500.34"
balance_int = int(float(balance_str))

# print the type
print(type(balance_int))

# print the value
print(balance_int)

Output


              
<class 'int'>
1500

If the string is a float numeral, you can convert it into a float type using float(), and then parse it to an integer using int().
