How to print one character at a time on one line?
Two tricks here, you need to use a stream to get everything in the right place and you also need to flush the stream buffer.
import time
import sys
def delay_print(s):
for c in s:
sys.stdout.write(c)
sys.stdout.flush()
time.sleep(0.25)
delay_print("hello world")
How to make Python print one character at a time on the same line?
A simple for
loop will get you the individual characters from any string. The only real trick is to flush the output after each character to make it print immediately.
import sys, time
for c in "Hello there!":
sys.stdout.write(c)
sys.stdout.flush()
time.sleep(0.1)
print
To make it a function is indeed simple:
def print1by1(text, delay=0.1):
for c in text:
sys.stdout.write(c)
sys.stdout.flush()
time.sleep(delay)
print
print1by1("Hello there!")
how to print one character at a time on one line using a METHOD
It looks like you're trying to create a delayed typing effect based on the first code snippet. The code there should be fine, all you need to do is migrate that code into a method so you can repeatedly create that delayed effect.
public void delay(String s, long delay) {
for ( int i= 0; i < s.length(); i++) {
// for loop delays individual String characters
System.out.print(s.charAt(i));
Thread.sleep(delay); //time is in milliseconds
}
System.out.println(""); // this is the space in between lines
}
Followed by a method call such as
delay("You are on a war-torn Plateau", 100L);
How do I print a single character multiple times on one line?
If you want to print everything in 1 line then you need to change from println to print.
I added another for loop to print the numbers in one line and added the line break after this loop.
for (int reverse = 9; reverse >= 1; reverse--) {
for (int i = 1; i <= reverse; i++)
System.out.print(reverse);
System.out.println(); // Line break after each number.
}
Output for the code above:
999999999
88888888
7777777
666666
55555
4444

I hope i understood clearly what you wanted.
Printing one character at a time from a string, using the while loop
I'm quite sure, that the internet is full of python while-loops, but one example:
i=0
while i < len(text):
print text[i]
i += 1
Print single character at a time in loop
Your output is being buffered: the output is held until a newline is sent, because printing a single line all at once is more efficient than printing it a character at a time.
You can put sys.stdout.flush()
after each print()
if you like. Other solutions here. Personally I kinda like the wrapper one. You can combine that with a context manager that sets and restores stdout
in a with
block for maximum Pythonicity.
Python writing one character per line instead of entire string on temporary file
read()
reads the entire contents of a file into a single array, that's why when you are iterating through it it prints each character on a separate line.
you need something like:
with open(tmp.name) as tmp:
new_division_text = tmp.readlines()
for line in new_division_text:
print(line)
note the readlines()
Quick Java String/toString Printing one char on each line
This would do the job:
String s = "someString";
for (int i = 0; i < s.length(); i++) {
System.out.println(s.charAt(i));
}
