如何在函数的同一行上打印数组的各个部分，而不留空格？

Question

我正试着一个字符一个字符地打印字符串，但中间总是有空白。似乎想不出如何摆脱它。有没有一种方法可以在没有空格的情况下仍然打印动画的字符串

    import time

    starting_text = 'Welcome to CHOOSE YOUR OWN ADVENTURE!' 
    new_starting_text = list(starting_text)

    for x in new_starting_text:
        print(x),
        time.sleep(.1)

Answer 1

不需要将字符串转换为列表，只需调用replace函数将空格替换为空字符串

starting_text = = 'Welcome to CHOOSE YOUR OWN ADVENTURE!' 
new_starting_text = starting_text.replace(" ", "")
#result = 'WelcometoCHOOSEYOUROWNADVENTURE!'

#to print it character by character you can loop through the new string
for x in new_starting_text:
    print(x)

希望这有帮助

Answer 2

尝试使用此修改后的代码：

import time
import sys

starting_text = 'Welcome to CHOOSE YOUR OWN ADVENTURE!'
new_starting_text = list(starting_text)

for x in new_starting_text:
    print(x,end = ''),
    sys.stdout.flush()
    time.sleep(.1)

std.stdout.flush（）将光标移回第一行，删除新行并保留所需的动画。希望这对你有帮助

对于Python 3

import time

starting_text = 'Welcome to CHOOSE YOUR OWN ADVENTURE!' 
new_starting_text = list(starting_text)

for x in new_starting_text:
    print(x, end='')
    time.sleep(.1)

输出

Welcome to CHOOSE YOUR OWN ADVENTURE!

对于Python 2

from __future__ import print_function
import time

starting_text = 'Welcome to CHOOSE YOUR OWN ADVENTURE!' 
new_starting_text = list(starting_text)

for x in new_starting_text:
    print(x, end='')
    time.sleep(.1)

输出

Welcome to CHOOSE YOUR OWN ADVENTURE!

从help(print)：

print(...)
    print(value, ..., sep='', end='\n', file=sys.stdout)

    Prints the values to a stream, or to sys.stdout by default.
    Optional keyword arguments:
    file: a file-like object (stream); defaults to the current sys.stdout.
    sep:  string inserted between values, default a space.
    end:  string appended after the last value, default a newline.
