input()
Reads a line from sys.stdin, strips the trailing newline, and returns it as a string. Optionally writes prompt to stdout first.
input(prompt='')Parameters
| Parameter | Purpose |
|---|---|
| prompt | Text written to stdout before reading input |
| returns | The line read as a str (newline stripped); EOFError at end-of-stream |
Examples
name = input('Name: ')Prompts then reads a line
n = int(input('n: '))Converts input to int (raises ValueError on bad input)
try:
line = input()
except EOFError:
line = ''Handles piped EOF
Gotcha
Always returns str — convert with int()/float() when needed. Raises EOFError on end-of-stream (e.g. Ctrl-D or piped input).
