How to convert python numbers to strings

Python numbers use the str() function, the format() method, f-strings and string concatenation to convert to strings. 1. str() function, which accepts a number as a parameter and converts it into a corresponding string; 2. format() method, which indicates the data to be inserted by using the placeholder {} in the format string. Numbers, and use the format() method to pass the numbers to the string; 3. f string, you can add the letter "f" in front of the string, and then use the variable name in curly braces, etc.

Python is a powerful programming language that provides many built-in functions and methods to handle conversion between different data types. This includes functionality to convert numbers to strings. In this article, we'll cover a few common ways to convert numbers to strings.

1. Use the str() function

The easiest way is to use the built-in str() function. This function accepts a number as an argument and converts it to the corresponding string. For example:

number = 123
string = str(number)
print(string) # 输出：'123'

2. Use the format() method

This method is implemented using the format() method of the string. You can indicate the number to insert by using the placeholder {} in the format string and passing the number to the string using the format() method. For example:

number = 123
string = '{}'.format(number)
print(string) # 输出：'123'

3. Using f string

from Python Starting from 3.6, the concept of f-string was also introduced. It's a cleaner way to embed expressions directly into strings. We can prepend the letter "f" to the string and then use a variable name or any legal Python expression within curly braces. For example:

number = 123
string = f'{number}'
print(string) # 输出：'123'

4. Using string concatenation

Another common way to convert numbers to strings is to use string concatenation. We can add the number to an empty string, which will force Python to convert the number to a string. For example:

number = 123
string = '' + str(number)
print(string) # 输出：'123'

It should be noted that the above methods can convert integers or floating point numbers into strings. However, if you want to convert numbers into strings in other bases (such as binary, hexadecimal, etc.), you can use the built-in functions bin(), oct(), and hex(). For example:

number = 123
binary = bin(number)
octal = oct(number)
hexadecimal = hex(number)
print(binary) # 输出：'0b1111011'
print(octal) # 输出：'0o173'
print(hexadecimal) # 输出：'0x7b'

In this article, we introduce several commonly used methods to convert numbers to strings, including using the str() function, format() method, f-string and string concatenation. These methods are useful for handling conversions between numbers and strings in Python. No matter which method you use, you can choose the most suitable method to implement your code according to your actual needs. .
