這 line=(f.readline(x))是類似的東西 (["content of file"]),即它是元組內列表中的文件內容。
您需要將其定義的大小x從 0 更改為某個值,或者不使用它。即 fromline = (f.readline(x))到line = f.readline()現在將是一個字符串。
現在您可以對字符串對象使用拆分操作。改成a, b = (line).split(':')_a, b = line.split(':')
所以新的代碼將是
# opening/cretaing a file and adding data
with open("scores.txt", 'a') as f:
f.write("\n")
f.write("andrew:78")
f.write("\n")
f.write("karen:64")
# creating a dictionary to save data of name and score respectively
scores = {'name':[], 'score':[]}
# again opening the file in read mode
with open("scores.txt", 'r') as f:
data = f.readlines() # reading all line in file at single time
for each_line in data:
if line.split(':'): # checking if each line has format <name>:<score> or not, if yes then add that data to scores dict
name, score = line.split(':')
scores['name'].append(name)
scores['score'].append(score)
# seeing the result
print(scores)

這段代碼能達到你想要的效果嗎?
with open("scores.txt", "a") as f:
f.write(
"\nandrew:78"
"\nkaren:64"
)
scores = []
with open("scores.txt", "r") as f:
lines = f.readlines()
for line in lines:
if ":" in line:
a, b = (line).split(":")
scores.append({a: b})
您可能遇到錯誤,因為某些行(空白行)沒有“:”,因此該行只是一個字符串,您試圖將其解壓縮為兩個變量。

它會在換行符 '\n' 之前打印出一個空字符 '' - 我認為你想要的是這樣的:
lines = f.read().splitlines()
#This will only get the value for one line
scores[0], scores[1] = lines[0].split(':')
#Or to get both lines:
i=0
for line in f.read().splitlines():
scores[i][0], scores[i][1] = line.split(':')
i += 1
