Question

我正在尝试组合一个程序，该程序将搜索整个文本文件的内容。该程序将针对字典搜索文本文件，并将找到的任何键替换为其字典值。我遇到了错误，不确定如何继续。

示例：字典= {key1：value1，key2：value2，key3：value3等...}

随机文本示例：之前实际上，所有Key1都会告诉他。 Key1坚持仅限于婚礼，Key2返回了Key3辩论。

之后实际上，所有Value1都会告诉他。 Value1坚持只限于婚礼Value2返回Value3辩论。

mappings = {

# Open file for substitution
replaceFile = open('as03_int.txt', 'r+')

# read in all the lines
lines = replaceFile.readlines()

# seek to the start of the file and truncate
replaceFile.seek(0)
replaceFile.truncate()

# Loop through each line from file
for line in lines:
    # Loop through each Key in the mappings dict
    for i in mappings.keys():
        # if the key appears in the line
        if i in line:
            print(line)
            # do replacement
            line = line.replace(i, mappings[i])
    # Print the line and move to next line
    print(line)

    if i in line:
TypeError: 'in <string>' requires string as left operand, not int

Answer 1

您应使用此经过更正的代码部分：

......
for i in mapping.keys():
    if str(i) in line:
        ......
