[英]How to get user input for multiline lines in Python 3?
我知道常規輸入函數可以接受單行,但是一旦您嘗試編寫一個字符串段落並按下回車鍵進入下一行,它就會終止。 是否有一種初學者友好的方式來接受多行用戶字符串輸入作為變量?
在程序中執行此操作的一種常見方法是使用“I'm done”字符串(例如單個句點),並繼續逐行讀取,直到讀取的行與該字符串匹配。
print("Enter as many lines of text as you want.")
print("When you're done, enter a single period on a line by itself.")
buffer = []
while True:
print("> ", end="")
line = input()
if line == ".":
break
buffer.append(line)
multiline_string = "\n".join(buffer)
print("You entered...")
print()
print(multiline_string)
你可以使用 sys 庫來做到這一點
import sys
x = sys.stdin.read()
def processString(x):
print(x.replace('process','whatever'))
lines = ""
while True:
if lines == "":
lines = ""
print("Enter string:")
x = input()
if x == "" and lines != "":
processString(lines)
break
else:
lines += x
# then hit enter once after multi-line string to process it
import sys
s = sys.stdin.read()
# print(s) # It will print everything
for line in s.splitlines(): # to read line by line
print(line)
[input() for i in range(int(input()))]
對於 n 多行用戶輸入,列表中的每個索引都是用戶輸入的新行。
Line=""
while True:
x=input()
Line=Line+" "+x
if "." in x:
break
print(Line)
