Handling Text file in Python (Writing Data in Text file)

Storing data in text file is one of the important work people use to do in any language. If you will go for C++ and Java, you have to write lots of code for doing and making connection of stream explicitly and have to import many additional libraries to do so.

But here in case of python you no need to worry about all these. You have to write just few line of code to write data into text file. Here is the sample code.

 fout = open("StuTextFile.txt","a+")
name = input("Enter your name : ")
addr = input("Enter address : ")
school = input("Enter school : ")
str = name+"\t"+addr+"\t"+school
fout.write(str)
fout.close()

Code description –

In first line of code a file “StuTextFile.txt” will get open in append mode so that data entered will get saved again and again without overwriting it in to file. As you know default file mode is r+ to read, w+ for write and a+ to append.

Second, third and fourth line is just to get input from user (name, addr, school). Fifth line is creating a string with tab space. Sixth line is the important line to call write() function on the file object created (fout). Last line is to close the file object. It means file object’s connection with file will be disconnected.

Python Compound Data Types
(List, Tuple, Dictionary and String)

Python Compound data type are most powerful datatypes in compare to other languages. Python having four most important data types (List, Tuple, Dictionary and String). Lets start discussing it in brief.

List

List is the very first compound data type in python that can hold multiple values like array and indexed. Data will be enclose within square braces [] and separated by comma. The difference between normal array and list is- list can hold multiple value of multiple data type where as array can hold only same kind of data. For example –

lst = [4, ,6.7, ‘Hello”, ‘c’]

Here a list is declared with name lst and holding an integer, a float, a string and a single character.

Tuple

Tuple s another compound data type in python that can hold multiple values and indexed. Like array or list but the elements of tuple is immutable (can not changed). Data will be enclose within parenthesis () and separated by comma. For example –

tpl= (4, ,6.7, ‘Hello”, ‘c’)

Here a Tuple is declared with name tpl and holding an integer, a float, a string and a single character.

Dictionary

A dictionary is a collection or compound data type which is unordered, changeable and indexed. In Python dictionaries are written with curly brackets, and they have keys and values.

dict = {'Name' :'Ramesh',
'age': 35,
'gender':'male',
'marks':98.5}

Here a Dictionary is declared with name dict and holding key value pair of name, age, gender and marks.

String

String literal are the datatype which is most common and most useful. You can store a String in double quotes or singe quotes. String is indexed data type and mutable in place.

strdq = "I am String literal" #String with double quotes
strsq = 'I am String literal'  #String with single quotes 
print(strdq)     #print string in python 
print(strsq)

Here a String is declared with strdq and strsq where strdq defined using double quotes and str sq defined using single quotes.
