Writing floating point numbers to a file in Python
Python makes writing data to a file a seamless task. The data is written to the file in the form of strings. In this article, you will learn how to write float values to a file in Python.
Writing floating point numbers to a file in Python
To write floating point numbers to a file in Python, we can use format strings. Format strings are special strings in Python that allow us to insert string representations of objects in a string. Unlike regular strings, format strings are fprefixed with . The following Python code describes how to use the discussed method.
data = [1234.342, 55.44257, 777.5733463467, 9.9999, 98765.98765]
f = open("output.txt", "w")
for d in data:
f.write(f"{d}\n")
f.close()
Output:
1234.342
55.44257
777.5733463467
9.9999
98765.98765
In addition to formatting strings, we can also use the built-in str()method to return a string representation of an object. We can use this method to convert floating point numbers to their string equivalents and write them to a file. See the following Python code.
data = [1234.342, 55.44257, 777.5733463467, 9.9999, 98765.98765]
f = open("output.txt", "w")
for d in data:
f.write(str(d))
f.write("\n")
f.close()
Output:
1234.342
55.44257
777.5733463467
9.9999
98765.98765
