### Overview
The **read()** method is used to read a specified number of characters (in text mode `t`) or bytes (in binary mode `b`) from a file. If the parameter **size** is not given or is negative, it reads the entire content of the file.
### Syntax
The syntax for the read() method is as follows:
fileObject.read();
### Parameters
* **size** -- The number of characters (in text mode) or bytes (in binary mode) to read from the file. The default is **-1**, which means the entire file is read.
### Return Value
Returns the bytes read from the string.
### Example
The following example demonstrates the use of the read() method:
The content of the file `.txt` is as follows:
This is line 1, this is line 2, this is line 3, this is line 4, this is line 5.
Looping to read the file content:
## Example
#!/usr/bin/python3
# Open the file
fo =open(".txt","r+")
print("File name: ", fo.name)
line = fo.read(10)
print("Read string: %s" % (line))
# Close the file
fo.close()
The output of the above example is:
File name: .txt Read string: This is the first line this is the second
